Deuteronomy 16:2

But unto the place which the Lord your God shall choose out of all your tribes to put his name there, even unto his habitation shall ye seek, and thither thou shalt come:

Only thy holy things which thou hast, and thy vows, thou shalt take, and go unto the place which the Lord shall choose:

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:

And Josiah gave to the people, of the flock, lambs and kids, all for the passover offerings, for all that were present, to the number of thirty thousand, and three thousand bullocks: these were of the king’s substance.

Then there shall be a place which the Lord your God shall choose to cause his name to dwell there; thither shall ye bring all that I command you; your burnt offerings, and your sacrifices, your tithes, and the heave offering of your hand, and all your choice vows which ye vow unto the Lord:

But in the place which the Lord shall choose in one of thy tribes, there thou shalt offer thy burnt offerings, and there thou shalt do all that I command thee.

But thou must eat them before the Lord thy God in the place which the Lord thy God shall choose, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite that is within thy gates: and thou shalt rejoice before the Lord thy God in all that thou puttest thine hands unto.

Thou shalt eat it before the Lord thy God year by year in the place which the Lord shall choose, thou and thy household.

Your lamb shall be without blemish, a male of the first year: ye shall take it out from the sheep, or from the goats: And ye shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening. And they shall take of the blood, and strike it on the two side posts and on the upper door post of the houses, wherein they shall eat it.

And he said unto them, With desire I have desired to eat this passover with you before I suffer:

And he sent Peter and John, saying, Go and prepare us the passover, that we may eat.

And the first day of unleavened bread, when they killed the passover, his disciples said unto him, Where wilt thou that we go and prepare that thou mayest eat the passover?

Now the first day of the feast of unleavened bread the disciples came to Jesus, saying unto him, Where wilt thou that we prepare for thee to eat the passover?

Ye know that after two days is the feast of the passover, and the Son of man is betrayed to be crucified.

And in the fourteenth day of the first month is the passover of the Lord. And in the fifteenth day of this month is the feast: seven days shall unleavened bread be eaten. In the first day shall be an holy convocation; ye shall do no manner of servile work therein: But ye shall offer a sacrifice made by fire for a burnt offering unto the Lord; two young bullocks, and one ram, and seven lambs of the first year: they shall be unto you without blemish:
