23 For the Lord will pass through striking the Egyptians: and when he shall see the blood on the transom, and on both the posts, he will pass over the door of the house, and not suffer the destroyer to come into your houses and to hurt you.
24 Thou shalt keep this thing as a law for thee and thy children for ever.
25 And when you have entered into the land which the Lord will give you as he hath promised, you shall observe these ceremonies.
26 And when your children shall say to you: What is the meaning of this service?
27 You shall say to them: It is the victim of the passage of the Lord, when he passed over the houses of the children of Israel in Egypt, striking the Egyptians, and saving our houses. And the people bowing themselves, adored.
28 And the children of Israel going forth did as the Lord had commanded Moses and Aaron.
29 And it came to pass at midnight, the Lord slew every firstborn in the land of Egypt, from the firstborn of Pharao, who sat on his throne, unto the firstborn of the captive woman that was in the prison, and all the firstborn of cattle.
