God commanded that the Passover feast be a sacrificed lamb. “Tell all the congregation of Israel that on the tenth day of this month they shall take every man a lamb according to their fathers’ houses” Ex 12:3 “You shall keep it until the fourteenth day of this month, when the whole assembly of the congregation of Israel shall kill their lambs in the evening” Ex 12:6 “They shall eat the flesh that night, roasted; with unleavened bread and bitter herbs they shall eat it” Ex 12:8.
And God commanded that the Passover feast be an ordinance forever: “This day shall be for you a memorial day, and you shall keep it as a feast to the Lord; throughout your generations you shall observe it as an ordinance for ever” Ex 12:14 For the feast they had to consume the body of a sacrificed lamb.
And God commanded that the Passover could only be celebrated in the Temple: “You shall seek the place which the Lord your God will choose out of all your tribes to put his name and make his habitation there; thither you shall go, and thither you shall bring your burnt offerings and your sacrifices, your tithes and the offering that you present, your votive offerings, your freewill offerings, and the firstlings of your herd and of your flock” Deut 12:5–6. It is significant that in the Torah God never mentioned a Temple. He said only, “The place which the Lord your God will choose.” This made it possible for him to choose the Temple in Solomon’s time, and Rabbi Yeshua in his time.
After AD 70 there was no Temple but, because God declared it eternal, it must be continuing in some form. Rabbi Yeshua continued the Passover Sacrifice during the Last Supper by instituting the Sacrament of His Body and Blood Mt 26:26–28. On that great Passover night God’s people Israel were saved from physical death by the body and blood of a sacrificed lamb Ex 12:8. In the most holy sacrament God’s people in the New Israel are saved by the body and blood of a sacrificed Lamb Jn 6:53–54.
