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.
22. And ye shall take a bunch of hyssop, and dip it in the blood that is in the basin, and strike the lintel and the two side-posts with the blood that is in the basin: and none of you shall go out at the door of his house till the morning.
23. For the LORD will pass through to smite the Egyptians; and when he seeth the blood upon the lintel, and on the two side-posts, the LORD will pass over the door, and will not suffer the destroyer to come in to your houses to smite you.
