18. The bread you eat must be made without yeast from the evening of the fourteenth day of the first month until the evening of the twenty-first day of that month.
19. During those seven days, there must be no trace of yeast in your homes. Anyone who eats anything made with yeast during this week will be cut off from the community of Israel. These regulations apply both to the foreigners living among you and to the native-born Israelites.
20. During those days you must not eat anything made with yeast. Wherever you live, eat only bread made without yeast.”

22. Drain the blood into a basin. Then take a bundle of hyssop branches and dip it into the blood. Brush the hyssop across the top and sides of the doorframes of your houses. And no one may go out through the door until morning.
23. For the lord will pass through the land to strike down the Egyptians. But when he sees the blood on the top and sides of the doorframe, the lord will pass over your home. He will not permit his death angel to enter your house and strike you down.
24. “Remember, these instructions are a permanent law that you and your descendants must observe forever.
25. When you enter the land the lord has promised to give you, you will continue to observe this ceremony.
26. Then your children will ask, ‘What does this ceremony mean?’
27. And you will reply, ‘It is the Passover sacrifice to the lord, for he passed over the houses of the Israelites in Egypt. And though he struck the Egyptians, he spared our families.’” When Moses had finished speaking, all the people bowed down to the ground and worshiped.
