21. Then Moses called all the elders of the sons of Israel, and he said to them: "Go, taking an animal by your families, and sacrifice the Passover.
22. And dip a little bundle of hyssop in the blood which is at the entrance, and sprinkle the upper threshold with it, and both of the door posts. Let none of you go out of the door of his house until morning.
23. For the Lord will cross through, striking the Egyptians. And when he will see the blood on the upper threshold, and on both the door posts, he will pass over the door of the house and not permit the Striker to enter into your houses or to do harm.
24. You shall keep this word as a law for you and for your sons, forever.
25. And when you have entered into the land that the Lord will give to you, just as he has promised, you shall observe these ceremonies.
