Exodus 12:13-15

Lexham English Bible

¹³ And the blood will be a sign for you on the houses where you are, and I will see the blood, and I will pass over you, and there will not be a destructive plague among you when I strike the land of Egypt.

¹⁴ “And this day will become a memorial for you, and you will celebrate it as a religious feast for Yahweh throughout your generations; you will celebrate it as a lasting statute. ¹⁵ You will eat unleavened bread for seven days. Surely on the first day you shall remove yeast from your houses, because anyone who eats food with yeast from the first day until the seventh day—that person will be cut off from Israel.
