17You shall observe the feast of unleavened bread; for in this same day have I brought your hosts out of the land of Egypt: therefore shall you observe this day throughout your generations by an ordinance forever.
18In the first month, on the fourteenth day of the month at evening, you shall eat unleavened bread, until the twenty first day of the month at evening.
19Seven days shall there be no yeast found in your houses, for whoever eats that which is leavened, that soul shall be cut off from the congregation of Israel, whether he be a sojourner, or one who is born in the land.
20You shall eat nothing leavened. In all your habitations you shall eat unleavened bread.`"
21Then Moses called for all the elders of Israel, and said to them, "Draw out, and take lambs according to your families, and kill the Passover.
22You 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 of the door of his house until the morning.
23For Yahweh will pass through to strike the Egyptians; and when he sees the blood on the lintel, and on the two side-posts, Yahweh will pass over the door, and will not allow the destroyer to come in to your houses to strike you.
