Observe the month of Abib, and keep the passover unto the Lord thy God: for in the month of Abib the Lord thy God brought thee forth out of Egypt by night.
It is a night to be much observed unto the Lord for bringing them out from the land of Egypt: this is that night of the Lord to be observed of all the children of Israel in their generations.
Thou shalt therefore sacrifice the passover unto the Lord thy God, of the flock and the herd, in the place which the Lord shall choose to place his name there.
