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. 24 You shall observe this rite as a statute for you and for your sons forever. 25 And when you come to the land that the Lord will give you, kas he has promised, you shall keep this service. 26 And lwhen your children say to you, ‘What do you mean by this service?’ 27 you shall say, m‘It is the sacrifice of the Lord’s Passover, for he passed over the houses of the people of Israel in Egypt, when he struck the Egyptians but spared our houses.’ ” And the people nbowed their heads and worshiped.

28 Then the people of Israel went and did so; as the Lord had commanded Moses and Aaron, so they did.
