The LORD said to Moses,
"Consecrate to me all the first-born; whatever is the first to open the womb among the people of Israel, both of man and of beast, is mine."
And Moses said to the people, "Remember this day, in which you came out from Egypt, out of the house of bondage, for by strength of hand the LORD brought you out from this place; no leavened bread shall be eaten.
This day you are to go forth, in the month of Abib.
And when the LORD brings you into the land of the Canaanites, the Hittites, the Amorites, the Hivites, and the Jeb'usites, which he swore to your fathers to give you, a land flowing with milk and honey, you shall keep this service in this month.
Seven days you shall eat unleavened bread, and on the seventh day there shall be a feast to the LORD.
Unleavened bread shall be eaten for seven days; no leavened bread shall be seen with you, and no leaven shall be seen with you in all your territory.
And you shall tell your son on that day, 'It is because of what the LORD did for me when I came out of Egypt.'
