Exodus 13:1-4

Then the Lord spoke to Moses, saying,

“Sanctify to Me every firstborn, the firstborn of every womb among the sons of Israel, among people and animals alike; it belongs to Me.”

And Moses said to the people, “Remember this day in which you departed from Egypt, from the house of slavery; for by a powerful hand the Lord brought you out from this place. And nothing with yeast shall be eaten.

On this day in the month of Abib, you are about to go out from here.
