¹⁷ And ye shall observe the feast of unleavened bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever.

⁴³ And the Lord said unto Moses and Aaron, This is the ordinance of the passover: There shall no stranger eat thereof:

⁹ And it shall be for a sign unto thee upon thine hand, and for a memorial between thine eyes, that the Lord's law may be in thy mouth: for with a strong hand hath the Lord brought thee out of Egypt.

¹⁰ Thou shalt therefore keep this ordinance in his season from year to year.

²¹ And the king commanded all the people, saying, Keep the passover unto the Lord your God, as it is written in the book of this covenant.
