Exodus 12:19-29

19 For those seven days not a trace of yeast is to be found in your houses. Anyone, whether a visitor or a native of the land, who eats anything raised shall be cut off from the community of Israel.
20 Don't eat anything raised. Only matzoth."
21 Moses assembled all the elders of Israel. He said, "Select a lamb for your families and slaughter the Passover lamb.
22 Take a bunch of hyssop and dip it in the bowl of blood and smear it on the lintel and on the two doorposts. No one is to leave the house until morning.
23 God will pass through to strike Egypt down. When he sees the blood on the lintel and the two door posts, God will pass over the doorway; he won't let the destroyer enter your house to strike you down with ruin.
24 "Keep this word. It's the law for you and your children, forever.
25 When you enter the land which God will give you as he promised, keep doing this.
26 And when your children say to you, 'Why are we doing this?'
27 tell them: 'It's the Passover-sacrifice to God who passed over the homes of the Israelites in Egypt when he hit Egypt with death but rescued us.'" The people bowed and worshiped.
28 The Israelites then went and did what God had commanded Moses and Aaron. They did it all.
29 At midnight God struck every firstborn in the land of Egypt, from the firstborn of Pharaoh, who sits on his throne, right down to the firstborn of the prisoner locked up in jail. Also the firstborn of the animals.
