¹⁷ You shall observe the feast of unleavened bread; for in this same day have I brought your armies out of the land of Egypt: therefore you shall observe this day throughout your generations by an ordinance forever.

²³ For Yahweh will pass through to strike the Egyptians; and when he sees the blood on the lintel, and on the two doorposts, Yahweh will pass over the door, and will not allow the destroyer to come in to your houses to strike you.
