Leviticus 23:9-11 (NASB, New American Standard Bible)
Then the LORD spoke to Moses, saying,  “Speak to the sons of Israel, and say to them, ‘When you enter the land which I am going to give to you and reap its harvest, then you shall bring in the sheaf of the first fruits of your harvest to the priest.  ‘And he shall wave the sheaf before the LORD for you to be accepted; on the day after the sabbath the priest shall wave it.
In the same way that Jesus Christ fulfilled the law concerning our Passover He also fulfilled the law concerning the wave sheaf and firstfruits.
We know that Jesus is “the Lamb of God” Who has been sacrificed for us and by the blood of His Sacrifice He cleanses us from sin. If Jesus died to cover our sins He had to be raised from the dead in order for that sacrifice to be fulfilled, so that we could receive the salvation that comes by His life.
1 Cor. 15:12-19 (NASB)
Now if Christ is preached, that He has been raised from the dead, how do some among you say that there is no resurrection of the dead?  But if there is no resurrection of the dead, not even Christ has been raised;  and if Christ has not been raised, then our preaching is vain, your faith also is vain.  Moreover we are even found to be false witnesses of God, because we witnessed against God that He raised Christ, whom He did not raise, if in fact the dead are not raised.  For if the dead are not raised, not even Christ has been raised;
 and if Christ has not been raised, your faith is worthless; you are still in your sins.  Then those also who have fallen asleep in Christ have perished.  If we have hoped in Christ in this life only, we are of all men most to be pitied.
The apostle Paul tells us that Joshua (Jesus) Messiah (Christ) has risen from the dead!
1 Cor. 15:20 (NASB)
But now Christ has been raised from the dead, the first fruits of those who are asleep.
1 Cor. 15:3-4 (NASB)
For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures,  and that He was buried, and that He was raised on the third day according to the Scriptures,
Romans 5:10 (NASB)
For if while we were enemies, we were reconciled to God through the death of His Son, much more, having been reconciled, we shall be saved by His life.
We are able to know the day Jesus Christ died and when He rose from the dead.
Jesus gave a sign to those who did not believe He was Messiah.
Matthew 12:38-41 (NASB)
Then some of the scribes and Pharisees answered Him, saying, “Teacher, we want to see a sign from You.”  But He answered and said to them, “An evil and adulterous generation craves for a sign; and yet no sign shall be given to it but the sign of Jonah the prophet;  for just as Jonah was three days and three nights in the belly of the sea monster, so shall the Son of Man be three days and three nights in the heart of the earth.  “The men of Nineveh shall stand up with this generation at the judgment, and shall condemn it because they repented at the preaching of Jonah; and behold, something greater than Jonah is here.
This is the only sign Jesus spoke of to those who did not believe that He is Messiah (Christ).
He spoke several times about being raised from the dead the third day.
Mark 9:31 (NASB)
For He was teaching His disciples and telling them, “The Son of Man is to be delivered into the hands of men, and they will kill Him; and when He has been killed, He will rise three days later.”
Mark 10:34 (NASB)
“And they will mock Him and spit upon Him, and scourge Him, and kill Him, and three days later He will rise again.”
John 2:19-22 (NASB)
Jesus answered and said to them, “Destroy this temple, and in three days I will raise it up.”  The Jews therefore said, “It took forty-six years to build this temple, and will You raise it up in three days?”  But He was speaking of the temple of His body.  When therefore He was raised from the dead, His disciples remembered that He said this; and they believed the Scripture, and the word which Jesus had spoken.
Matthew 16:21 (NASB)
From that time Jesus Christ began to show His disciples that He must go to Jerusalem, and suffer many things from the elders and chief priests and scribes, and be killed, and be raised up on the third day.
Matthew 17:23 (NASB)
…and they will kill Him, and He will be raised on the third day.” And they were deeply grieved.
Matthew 20:19 (NASB)
…and will deliver Him to the Gentiles to mock and scourge and crucify Him, and on the third day He will be raised up.”
Luke 9:22 (NASB)
…saying, “The Son of Man must suffer many things, and be rejected by the elders and chief priests and scribes, and be killed, and be raised up on the third day.”
Luke 18:33 (NASB)
…and after they have scourged Him, they will kill Him; and the third day He will rise again.”
Luke 24:7 (NASB)
…saying that the Son of Man must be delivered into the hands of sinful men, and be crucified, and the third day rise again.”
There is a specific day and time given when someone witnessed Jesus (Joshua) being alive and risen from the dead.
John 20:1 (NASB)
Now on the first day of the week Mary Magdalene came early to the tomb, while it was still dark, and saw the stone already taken away from the tomb.
John 20:16-17 (NASB)
…Jesus said to her, “Mary!” She turned and said to Him in Hebrew, “Rabboni!” (which means, Teacher).
 Jesus said to her, “Stop clinging to Me, for I have not yet ascended to the Father; but go to My brethren, and say to them, ‘I ascend to My Father and your Father, and My God and your God.’ “
The First Day of the week began at sunset as The Sabbath (The Seventh Day of the week) ends.
Leviticus 23:32 (NASB)
…from evening until evening you shall keep your Sabbath.
We now know that Jesus had already risen from the dead by the time that Mary met Him during the darkness part of The First Day of the week (“Sunday”).
Now we must determine when He was placed in the tomb.
Mark 15:42-47 (NASB)
And when evening had already come, because it was the preparation day, that is, the day before the Sabbath,  Joseph of Arimathea came, a prominent member of the Council, who himself was waiting for the kingdom of God; and he gathered up courage and went in before Pilate, and asked for the body of Jesus.
And Pilate wondered if He was dead by this time, and summoning the centurion, he questioned him as to whether He was already dead.  And ascertaining this from the centurion, he granted the body to Joseph.  And Joseph bought a linen cloth, took Him down, wrapped Him in the linen cloth, and laid Him in a tomb which had been hewn out in the rock; and he rolled a stone against the entrance of the tomb.  And Mary Magdalene and Mary the mother of Joses were looking on to see where He was laid.
John 19:31 (NASB)
The Jews therefore, because it was the day of preparation, so that the bodies should not remain on the cross on the Sabbath (for that Sabbath was a high day), asked Pilate that their legs might be broken, and that they might be taken away.
John 19:38-42 (NASB)
And after these things Joseph of Arimathea, being a disciple of Jesus, but a secret one, for fear of the Jews, asked Pilate that he might take away the body of Jesus; and Pilate granted permission. He came therefore, and took away His body.  And Nicodemus came also, who had first come to Him by night; bringing a mixture of myrrh and aloes, about a hundred pounds weight.  And so they took the body of Jesus, and bound it in linen wrappings with the spices, as is the burial custom of the Jews.  Now in the place where He was crucified there was a garden; and in the garden a new tomb, in which no one had yet been laid.  Therefore on account of the Jewish day of preparation, because the tomb was nearby, they laid Jesus there.
So Jesus was laid in the tomb near sunset on “the day of preparation” (“for that Sabbath was a high day“). The preparation day spoken of here is NOT a day of preparation for the weekly (Seventh Day of the week) Sabbath, but rather it was the preparation day for a special “high day“, or The First Day of Unleavened Bread, of Leviticus 23.
Leviticus 23:6-8 (NASB)
‘Then on the fifteenth day of the same month there is The Feast of Unleavened Bread to the Lord; for seven days you shall eat unleavened bread.  ‘On the first day you shall have a holy convocation; you shall not do any laborious work.  ‘But for seven days you shall present an offering by fire to the Lord. On the seventh day is a holy convocation; you shall not do any laborious work.’ “
The First Day of Unleavened Bread is the “high day” Sabbath mentioned in John 19:31.
Matthew 27:57-63 (NASB)
And when it was evening, there came a rich man from Arimathea, named Joseph, who himself had also become a disciple of Jesus.  This man went to Pilate and asked for the body of Jesus. Then Pilate ordered it to be given over to him.  And Joseph took the body and wrapped it in a clean linen cloth,  and laid it in his own new tomb, which he had hewn out in the rock; and he rolled a large stone against the entrance of the tomb and went away.  And Mary Magdalene was there, and the other Mary, sitting opposite the grave.
 Now on the next day, which is the one after the preparation, the chief priests and the Pharisees gathered together with Pilate,  and said, “Sir, we remember that when He was still alive that deceiver said, ‘After three days I am to rise again.’
Luke 23:50-55 (NASB)
And behold, a man named Joseph, who was a member of the Council, a good and righteous man  (he had not consented to their plan and action), a man from Arimathea, a city of the Jews, who was waiting for the kingdom of God;  this man went to Pilate and asked for the body of Jesus.  And he took it down and wrapped it in a linen cloth, and laid Him in a tomb cut into the rock, where no one had ever lain.  And it was the preparation day, and the Sabbath was about to begin.
 Now the women who had come with Him out of Galilee followed after, and saw the tomb and how His body was laid.
We have proven Joshua (Jesus) was already risen from the dead “… on the first day of the week …” “… while it was still dark…” (this would be what is referred to as “Saturday night”).
We have also proven that after His death He was placed in the tomb very close to sunset on a preparation day for The First Day of Unleavened Bread (“The Sabbath“, “a high day“).
We know that the sign He had given to unbelievers that He was Messiah (Christ) was “… so shall the Son of Man be three days and three nights in the heart of the earth.“.
If Jesus was put in the tomb just before sunset, then He would have risen from the dead JUST BEFORE sunset three days and three nights later.
By these things, we can know He raised from the dead JUST BEFORE sunset The Seventh Day of the week (on the weekly Sabbath), because He was seen during the darkness of The First Day of the week (Saturday night).
The day following Jesus’ death and burial the chief priests and Pharisees placed a seal on the stone which had been rolled in place at the entrance of the tomb and set guards to watch the area. No one would be allowed to visit the tomb while the guards and seal were in place.
Matthew 27:62-66 (NASB)
Now on the next day, which is the one after the preparation, the chief priests and the Pharisees gathered together with Pilate,  and said, “Sir, we remember that when He was still alive that deceiver said, ‘After three days I am to rise again.’
 “Therefore, give orders for the grave to be made secure until the third day, lest the disciples come and steal Him away and say to the people, ‘He has risen from the dead,’ and the last deception will be worse than the first.”  Pilate said to them, “You have a guard; go, make it as secure as you know how.”  And they went and made the grave secure, and along with the guard they set a seal on the stone.
Remember, Mary Magdalene saw Jesus the first time she visited the tomb following His resurrection from the dead “on the first day of the week Mary Magdalene came early to the tomb, while it was still dark“.
The guards were no longer there and the seal was broken and the stone rolled aside.
John 20:1, (NASB)
Now on the first day of the week Mary Magdalene came early to the tomb, while it was still dark, and saw the stone already taken away from the tomb.
Peter and “the other disciple” also saw the empty tomb.
John 20:2-10 (NASB)
And so she ran and came to Simon Peter, and to the other disciple whom Jesus loved, and said to them, “They have taken away the Lord out of the tomb, and we do not know where they have laid Him.”  Peter therefore went forth, and the other disciple, and they were going to the tomb.  And the two were running together; and the other disciple ran ahead faster than Peter, and came to the tomb first;  and stooping and looking in, he saw the linen wrappings lying there; but he did not go in.  Simon Peter therefore also came, following him, and entered the tomb; and he beheld the linen wrappings lying there,  and the face-cloth, which had been on His head, not lying with the linen wrappings, but rolled up in a place by itself.  So the other disciple who had first come to the tomb entered then also, and he saw and believed.  For as yet they did not understand the Scripture, that He must rise again from the dead.  So the disciples went away again to their own homes.
 But Mary was standing outside the tomb weeping; and so, as she wept, she stooped and looked into the tomb;  and she beheld two angels in white sitting, one at the head, and one at the feet, where the body of Jesus had been lying.  And they said to her, “Woman, why are you weeping?” She said to them, “Because they have taken away my Lord, and I do not know where they have laid Him.”
 When she had said this, she turned around, and beheld Jesus standing there, and did not know that it was Jesus.
 Jesus said to her, “Woman, why are you weeping? Whom are you seeking?” Supposing Him to be the gardener, she said to Him, “Sir, if you have carried Him away, tell me where you have laid Him, and I will take Him away.”
 Jesus said to her, “Mary!” She turned and said to Him in Hebrew, “Rabboni!” (which means, Teacher).
 Jesus said to her, “Stop clinging to Me, for I have not yet ascended to the Father; but go to My brethren, and say to them, ‘I ascend to My Father and your Father, and My God and your God.’ ”
 Mary Magdalene came, announcing to the disciples, “I have seen the Lord,” and that He had said these things to her.
Notice the four separate events concerning Jesus (Joshua) Christ (Messiah) being risen from the dead.
– John 20, Mary Magdalene, Peter and “the other disciple” visit the tomb while it is still dark on the 1st day of the week (what would now be considered saturday night). Mary saw Jesus alive.
– In Matthew 28 Mary Magdalene visits the tomb the second time with “the other Mary” as daylight (dawn) is beginning.
– Mark 16 records Mary Magdalene coming to the tomb the third time with “Mary the mother of James” (“the other Mary” Matthew 28:1) and Salome “when the sun had risen.(NASB)” “at the rising of the sun. (KJV)”.
– Luke 24 shows that Mary Magdalene comes to the tomb the fourth time with “Joanna and Mary the mother of James; also the other women”, “very early in the morning …(KJV)”, “at early dawn, (NASB)”.
“… Touch me not; …”
John 20:16-17 (NASB)
Jesus said to her, “Mary!” She turned and said to Him in Hebrew, “Rabboni!” (which means, Teacher).  Jesus said to her, “Stop clinging* to Me, for I have not yet ascended to the Father; but go to My brethren, and say to them, ‘I ascend to My Father and your Father, and My God and your God.’ “
Notice that the NASB Dictionary lists that the Greek word* has been translated only once as “clinging*”, 13 times as “touch**”, and 19 times as “touched***”.
NASB Dictionary Help Greek 681, NASB hapto*; from a primitive root ap or aph; to fasten to, lay hold of :- clinging(1)*, handle(1), kindled(1), light(1), lighting(2), touch(13)**, touched(19)***, touching(1).
The following are examples using same Greek word:
Mark 5:27-28 (NASB)
…after hearing about Jesus, came up in the crowd behind Him, and touched His cloak.  For she thought, “If I just touch His garments, I shall get well.” proceeding from Him had gone forth, turned around in the crowd and said, “Who touched My garments?”  And His disciples said to Him, “You see the multitude pressing in on You, and You say, ‘Who touched Me?’ “
2 Cor. 6:17 (NASB)
“Therefore, come out from their midst and be separate,” says the Lord.
“And do not TOUCH WHAT IS UNCLEAN;
And I will welcome you.
The King James Version of The Holy Bible translates it correctly.
John 20:17 (KJV, King James Version)
Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.
Mary Magdalene sees Him a second time when she goes to the tomb with “the other Mary” “…after the Sabbath, as it began to dawn (become daylight) toward The First Day of the week,”.
Matthew 28:1 (NASB) Now after the Sabbath, as it began to dawn toward the first day of the week, Mary Magdalene and the other Mary came to look at the grave.
When Mary Magdalene, Peter and “the other disciple” had first visited during the night after the Sabbath (John 20) there were no guards and the stone had been rolled away from the entrance of the tomb. Matthew inserts the record of an event which had already taken place.
Matthew 28:2-4 (NASB)
And behold, a severe earthquake had occurred, for an angel of the Lord descended from heaven and came and rolled away the stone and sat upon it.  And his appearance was like lightning, and his garment as white as snow;  and the guards shook for fear of him, and became like dead men.
Mtt.28:1 shows us that Mary Magdalene (this is her 2nd visit to the tomb) and the other Mary going to the tomb as daylight is just beginning, and it is the angel of verse 2-4 who is speaking to them.
Matthew 28:5-10 (NASB)
And the angel answered and said to the women, “Do not be afraid; for I know that you are looking for Jesus who has been crucified.  “He is not here, for He has risen, just as He said. Come, see the place where He was lying.  “And go quickly and tell His disciples that He has risen from the dead; and behold, He is going before you into Galilee, there you will see Him; behold, I have told you.”  And they departed quickly from the tomb with fear and great joy and ran to report it to His disciples.  And behold, Jesus met them and greeted them. And they came up and took hold of His feet and worshiped Him.  Then Jesus said to them, “Do not be afraid; go and take word to My brethren to leave for Galilee, and there they shall see Me.”
Notice in verse 9 the two women “… took hold of His feet and worshiped Him.” and Jesus says nothing to them about not touching Him.
He has already ascended to The Father (after the dawn on the First Day of the week) so there was no need for them not to touch Him.
Joshua (Jesus) Messiah (Cheist – Anointed) had fulfilled the sacrifice for our sins and that sacrifice was accepted by God for us.
Isaiah 53:11 (NASB)
As a result of the anguish of His soul,
He will see it and be satisfied;
By His knowledge the Righteous One,
My Servant, will justify the many,
As He will bear their iniquities.
Jesus (Joshua) Christ (Messiah – Anointed) The Sheaf (first product) of the firstfruits before The LORD, fulfilled the offering of The Wave Sheaf.
Leviticus 23:10-11 (NASB)
“Speak to the sons of Israel, and say to them, ‘When you enter the land which I am going to give to you and reap its harvest, then you shall bring in the sheaf of the first fruits of your harvest to the priest.  ‘And he shall wave the sheaf before the LORD for you to be accepted; on the day after the sabbath the priest shall wave it.
Hebrews 1:1-3 (NASB)
God, after He spoke long ago to the fathers in the prophets in many portions and in many ways,  in these last days has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world.
 And He is the radiance of His glory and the exact representation of His nature, and upholds all things by the word of His power. When He had made purification of sins, He sat down at the right hand of the Majesty on high;
Hebrews 8:1 (NASB)
Now the main point in what has been said is this: we have such a high priest, who has taken His seat at the right hand of the throne of the Majesty in the heavens,
Hebrews 9:24 (NASB)
For Christ did not enter a holy place made with hands, a mere copy of the true one, but into heaven itself, now to appear in the presence of God for us;
Romans 8:34 (NASB)
who is the one who condemns? Christ Jesus is He who died, yes, rather who was raised, who is at the right hand of God, who also intercedes for us.
He is alive! His sacrifice has been fulfilled for us to be accepted by the Father!
Joshua (Jesus) Messiah (Anointed – Christ) was killed and was placed in a tomb on The 14th Day of the First Month (“Abib” or “Nisen”), very near sunset.
1 Cor. 5:7 (NASB)
… For Christ our Passover also has been sacrificed.
He laid in the tomb three days and three nights.
The 1st night was The Fifth Day of the week [which began at sunset of The Fourth Day of the week- known as, “wednesday night”].
The 1st daylight was The Fifth Day of the week [“Thursday”].
The 2nd night was The Sixth Day of the week[“Thursday night”].
The 2nd daylight was The Sixt Day of the week [“Friday”].
The 3rd night was The Seventh Day of the week [a weekly Sabbath; a “Friday night”].
Finally, the 3rd daylight was The Seventh Day of the week [a weekly Sabbath].
Jesus raised from the dead very near sunset on The Seventh Day of the week (a Sabbath).
He ascended to the Father shortly after daylight on The First Day of the week (“Sunday” morning), fulfilling the role as our Wave Sheaf Offering.
Hebrews 7:22-25 (NASB)
…so much the more also Jesus has become the guarantee of a better covenant.  And the former priests, on the one hand, existed in greater numbers, because they were prevented by death from continuing,  but He, on the other hand, because He abides forever, holds His priesthood permanently.  Hence, also, He is able to save forever those who draw near to God through Him, since He always lives to make intercession for them.
The calendar that God gave to Israel is not the calendar used by most of the world today. God’s calendar is caculated by the moon, stars and sun.
The Hebrew calendar is used by Jews today.
The annual holy convocations do not always fall on the same day of the week every year. The example presented is for how the week would unfold for any year that aligns with the Biblical account of our Lord’s death and resurrection.
Notations are posted which deal with Jesus’ death, burial, resurrection, and other relevant events:
1st Month of the year, “Abib” or “Nisan”

Day of Month18(C)—–19———20———-21**……
14 (A)Joshua (Jesus) Messiah (Christ) “Lamb of God” was killed between the 9th and 10 hour, and placed in the tomb very close to sunset. This was also The Holy Passover of The LORD God (“the 14th Day, at even”- Exod. 12:18-19; Lev. 23:5; 1 Cor. 5:7).
15 *This was The First Day of Unleavened Bread (an holy convocation). It was at this time that the Jews had Jesus’ tomb sealed and a guard set, in order to prevent His disciples from stealing his body on the 3rd day and saying that He had risen…
17 (B)An great earthquake occurred at this time (Matt. 28:4), and Jesus was raised from the dead very close to sunset on The Seventh Day Sabbath; fulfilling the end of “Three days, and three nights in the heart of the earth“…
18 (C)Jesus ascends to His Father shortly after daylight on this First Day of The Week. This was also the moment when The High Priest would have offer the wave-sheaf of the firstfruits offering to The LORD God of Israel… Jesus Christ fulfilled the part of our wave-sheaf offering (- the first of the firstfruits). The “Count Fifty” would begin on this day and would end on the 50th Day, known as “Pentecost”, “The Day (Feast) of Firstfruits”, and “The Feast of Weeks”…(Lev. 23:15-16; Deut. 16:9-10; 1 Cor. 15:20-23)
21 **Seventh Day of Unleavened Bread (an holy convocation)- ending the holy feast week of Unleavened Bread.
Firstfruits – (Pentecost)
We have proven that Joshua (Jesus) Messiah (Anointed – Christ) fulfilled the wave sheaf before the Father in order for us to be accepted. Now we must determine the time of the next holy convocation of the LORD.
Leviticus 23:15-16 (NASB)
‘You shall also count for yourselves from the day after the sabbath, from the day when you brought in the sheaf of the wave offering; there shall be seven complete sabbaths.
 ‘You shall count fifty days to the day after the seventh sabbath; then you shall present a new grain offering to the Lord.
Leviticus 23:17-21 (NASB)
‘You shall bring in from your dwelling places two loaves of bread for a wave offering, made of two-tenths of an ephah; they shall be of a fine flour, baked with leaven as first fruits to the Lord.  ‘Along with the bread, you shall present seven one year old male lambs without defect, and a bull of the herd, and two rams; they are to be a burnt offering to the Lord, with their grain offering and their libations, an offering by fire of a soothing aroma to the Lord.  ‘You shall also offer one male goat for a sin offering and two male lambs one year old for a sacrifice of peace offerings.
 ‘The priest shall then wave them with the bread of the first fruits for a wave offering with two lambs before the Lord; they are to be holy to the Lord for the priest.
 ‘On this same day you shall make a proclamation as well; you are to have a holy convocation. You shall do no laborious work. It is to be a perpetual statute in all your dwelling places throughout your generations.
We know that Jesus had already fulfilled the wave sheaf by the time Mary Magdalene and the “other Mary” held His feet and worshipped Him a short time after daylight on The First Day of the week.
This being established, we are to count 50 days, “to the day after the seventh sabbath” and there is to be “an holy convocation“; a feast to The LORD.
This day is referred to as “The Feast of Weeks”, or “Pentecost” (Pentecost is a Greek word meaning – “count fifty” or “50th”).
The Seventh Day Sabbath (Saturday) which we count from must be during The Days of Unleavened Bread.
The holy convocation of The Feast of Weeks (or Pentecost) will always be observed on The First Day of the week (a “Sunday”) following the 7th Sabbath in the count.
The Feast of Weeks (or Pentecost) is the holy convocation which was being observed by the apostles and disciples of Joshua (Jesus), about ten days following His return to His and our Father in heaven.
They were given the gift of His Holy Spirit to begin “The Church of God”, “The Body of Joshua (Jesus) Messiah (Christ)”.
Acts 2:1-4 (NASB)
And when the day of Pentecost had come, they were all together in one place.  And suddenly there came from heaven a noise like a violent, rushing wind, and it filled the whole house where they were sitting.  And there appeared to them tongues as of fire distributing themselves, and they rested on each one of them.  And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit was giving them utterance.
The apostles spoke with Jews from many different countries and languages on this very special day.
Acts 2:5-13 (NASB)
Now there were Jews living in Jerusalem, devout men, from every nation under heaven.  And when this sound occurred, the multitude came together, and were bewildered, because they were each one hearing them speak in his own language.
 And they were amazed and marveled, saying, “Why, are not all these who are speaking Galileans?  “And how is it that we each hear them in our own language to which we were born?  “Parthians and Medes and Elamites, and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia,  Phrygia and Pamphylia, Egypt and the districts of Libya around Cyrene, and visitors from Rome, both Jews and proselytes,  Cretans and Arabs– we hear them in our own tongues speaking of the mighty deeds of God.”  And they all continued in amazement and great perplexity, saying to one another, “What does this mean?”  But others were mocking and saying, “They are full of sweet wine.”
The apostle Peter was speaking to the Jews of Judah and Jerusalem about Messiah.
Acts 2:14-36 (NASB)
But Peter, taking his stand with the eleven, raised his voice and declared to them: “Men of Judea, and all you who live in Jerusalem, let this be known to you, and give heed to my words.  “For these men are not drunk, as you suppose, for it is only the third hour of the day;  but this is what was spoken of through the prophet Joel:
 ‘And it shall be in the last days,’ God says,
‘That I will pour forth of My Spirit upon all MANKIND;
And your sons and your daughters shall prophesy,
And your young men shall see visions,
And your old men shall dream dreams;
 Even upon My bondslaves, both men and women,
I will in those days pour forth of My Spirit
And they shall prophesy.
 ‘And I will grant wonders in the sky above,
And signs on the earth beneath,
Blood, and fire, and vapor of smoke.
 ‘The sun shall be turned into darkness,
And the moon into blood,
Before the great and glorious day of the Lord shall come.
 ‘And it shall be, that EVERYONE WHO CALLS ON THE NAME OF THE Lord shall be saved.’
 “Men of Israel, listen to these words: Jesus the Nazarene, a man attested to you by God with miracles and wonders and signs which God performed through Him in your midst, just as you yourselves know–  this Man, delivered up by the predetermined plan and foreknowledge of God, you nailed to a cross by the hands of godless men and put Him to death.  “And God raised Him up again, putting an end to the agony of death, since it was impossible for Him to be held in its power.  “For David says of Him,
‘I was always beholding the Lord in my presence;
For He is at my right hand, that I may not be shaken.
 ‘Therefore my heart was glad and my tongue exulted;
Moreover my flesh also will abide in hope;
 Because Thou wilt not abandon my soul to Hades,
Nor ALLOW Thy Holy One to UNDERGO DECAY.
 ‘Thou hast made known to me the ways of life;
Thou wilt make me full of gladness with Thy presence.’
 “Brethren, I may confidently say to you regarding the patriarch David that he both died and was buried, and his tomb is with us to this day.  “And so, because he was a prophet, and knew that God had sworn to him with an oath to seat one of his descendants upon his throne,  he looked ahead and spoke of the resurrection of the Christ, that He was neither abandoned to Hades, nor did His flesh suffer decay.  “This Jesus God raised up again, to which we are all witnesses.  “Therefore having been exalted to the right hand of God, and having received from the Father the promise of the Holy Spirit, He has poured forth this which you both see and hear.  “For it was not David who ascended into heaven, but he himself says:
‘The Lord said to my Lord,
“Sit at My right hand,
 Until I make Thine enemies a footstool for Thy feet.” ‘
 “Therefore let all the house of Israel know for certain that God has made Him both Lord and Christ– this Jesus whom you crucified.”
Those listening to Peter speak were convicted in their mind (heart). Notice their reaction.
Acts 2:37 (NASB)
Now when they heard this, they were pierced to the heart, and said to Peter and the rest of the apostles, “Brethren, what shall we do?”
Peter gave an answer which is the same answer today for anyone who may be drawn to Jesus (Joshua) Christ (Messiah) for salvation.
Acts 2:38-39 (NASB)
And Peter said to them, “Repent, and let each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you shall receive the gift of the Holy Spirit.
 “For the promise is for you and your children, and for all who are far off, as many as the Lord our God shall call to Himself.”
God, our Father through Joshua (Jesus) Messiah (Christ – Anointed), began His Church on “The Day of Firstfruits”, or “The Feast of Weeks”, or “Pentecost”.
Acts 2:40-47 (NASB)
And with many other words he solemnly testified and kept on exhorting them, saying, “Be saved from this perverse generation!”  So then, those who had received his word were baptized; and there were added that day about three thousand souls.  And they were continually devoting themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer.
 And everyone kept feeling a sense of awe; and many wonders and signs were taking place through the apostles.  And all those who had believed were together, and had all things in common;  and they began selling their property and possessions, and were sharing them with all, as anyone might have need.  And day by day continuing with one mind in the temple, and breaking bread from house to house, they were taking their meals together with gladness and sincerity of heart,  praising God, and having favor with all the people. And the Lord was adding to their number day by day those who were being saved.
Today God adds to His Church exactly the same way He did then.

Jesus (Joshua) Christ (Messiah) is The Firstfruits alive from the dead:
1 Cor. 15:20-23 (NASB)
But now Christ has been raised from the dead, the first fruits of those who are asleep.  For since by a man came death, by a man also came the resurrection of the dead.  For as in Adam all die, so also in Christ all shall be made alive.  But each in his own order: Christ the first fruits, after that those who are Christ’s at His coming,
Those who have repented, been baptized, in the Name of Jesus Christ and received the Gift of God’s Holy Spirit are “a kind of firstfruits” in this world.
James 1:18 (NASB)
In the exercise of His will He brought us forth by the word of truth, so that we might be, as it were*, the first fruits among** His creatures.
NASB (margin notes):
* Lit., a certain first fruits
** Lit., of
We are to observe “The Day of Firstfruits”, also called “The Feast of Weeks”, also called “Pentecost” fifty days AFTER Joshua (Jesus) raised from the dead.
Let us rejoice before God on His Holy Convocations.
