15. Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whoever eateth leavened bread, from the first day till the seventh day, that soul shall be cut off from Israel.
16. And in the first day there shall be a holy convocation, and in the seventh day there shall be a holy convocation to you: no manner of work shall be done in them, save that which every man must eat, that only may be done by you.
17. And ye shall observe the feast of unleavened bread; for in this same 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.
18. In the first month, on the fourteenth day of the month at evening, ye shall eat unleavened bread, till the one and twentieth day of the month at evening.
19. Seven days shall there be no leaven found in your houses: for whoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he shall be a stranger, or born in the land.
20. Ye shall eat nothing leavened: in all your habitations shall ye eat unleavened bread.
21. Then Moses called for all the elders of Israel, and said to them, Draw out, and take you a lamb, according to your families, and kill the passover.
