Leviticus 23:5 In the fourteenth day of the first month at even is the LORD'S Passover.
Jesus was nailed to the cross at the third hour (9 am) and died at the 9th hour (3 p.m.). The exact times of the morning and evening sacrifices.
1 Corinthians 5:7 Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our Passover is sacrificed for us:
Leviticus 23:6 And on the fifteenth day of the same month is the feast of unleavened bread unto the LORD: seven days ye must eat unleavened bread.
Jesus was without sin: Hebrews 4:15 For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
1Corinthians 5:8 Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.
see also Luke 12:1;
Leviticus 23:11 And he shall wave the sheaf before the LORD, to be accepted for you: on the morrow after the sabbath the priest shall wave it.
1 Corinthians 15:20 But now is Christ risen from the dead, and become the first fruits of them that slept.
1 Corinthians 15:23 But every man in his own order: Christ the first fruits; afterward they that are Christs at his coming.
Deuteronomy 16:9 Seven weeks shalt thou number unto thee: begin to number the seven weeks from such time as thou beginnest to put the sickle to the corn.
Deuteronomy 16:10 And thou shalt keep the feast of weeks unto the LORD thy God with a tribute of a freewill offering of thine hand, which thou shalt give unto the LORD thy God, according as the LORD thy God hath blessed thee:
Acts 2:1 And when the day of Pentecost was fully come, they were all with one accord in one place.
Acts 2: 2 And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.
Acts 2: 3 And there appeared unto them cloven tongues like as of fire, and it sat upon each of them.
Acts 2: 4 And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
Seven is God's perfect number.
All the annual feasts were prophetic as well as typical. While the Passover lamb, slain each year, was a shadow of "Christ our Passover," who was sacrificed for us, the fact that the lamb could be slain only on the fourteenth day of the month Abib, was a prophecy that the anti typical Passover lamb would yield up His life for the sins of the world on the fourteenth day of Abib.
One unanswerable argument that Jesus is the Messiah, is that He died upon the cross the very day, that God had said the Passover lamb should be slain (1Corinthians. 5:7); and He came forth from the dead the same day of the month, that the first fruits had been waved for centuries (Colossians 1:18). God Himself, definitely fixed the date for the celebration of each of the annual offerings.
The day of the year when the annual offering was to be celebrated, was a direct prophecy of the time when the type would meet its antitype.
