In the fourteenth day of this month, at even, ye shall keep it in his appointed season: according to all the rites of it, and according to all the ceremonies thereof, shall ye keep it.
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.
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.
