17 And you shall observe the Feast of Unleavened Bread, for yon this very day I brought your zhosts out of the land of Egypt. Therefore you shall observe this day, throughout your generations, as a statute forever. 18 aIn the first month, from the fourteenth day of the month at evening, you shall eat unleavened bread until the twenty-first day of the month at evening. 19 bFor seven days no leaven is to be found in your houses. If anyone eats what is leavened, bthat person will be cut off from the congregation of Israel, cwhether he is a sojourner or a native of the land. 20 You shall eat nothing leavened; in all your dwelling places you shall eat unleavened bread.”

21 Then Moses called all the elders of Israel and said to them, “Go and select lambs for yourselves daccording to your clans, and kill the Passover lamb. 22 Take a bunch of ehyssop and fdip it in the blood that is in the basin, and touch gthe lintel and the two doorposts with the blood that is in the basin. hNone of you shall go out of the door of his house until the morning. 23 iFor the Lord will pass through to strike the Egyptians, and when he sees the blood on gthe lintel and on the two doorposts, the Lord will pass over the door and jwill not allow the destroyer to enter your houses to strike you.
