²³ For the LORD will pass through to smite the Egyptians; and when he seeth the blood upon the lintel, and on the two side-posts, the LORD will pass over the door, and will not suffer the destroyer to come in to your houses to smite you.

⁷ And they shall take of the blood, and strike it on the two side-posts, and on the upper door-post of the houses, in which they shall eat it.
