Exodus 12:23-25

Douay-Rheims 1899 American Edition

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.
