The Lord said to Moses,
"Dedicate all the first-born males to me, for every first-born male Israelite and every first-born male animal belongs to me." 13
Moses said to the people, "Remember this day - the day on which you left Egypt, the place where you were slaves. This is the day the Lord brought you out by his great power. No leavened bread is to be eaten.
You are leaving Egypt on this day in the first month, the month of Abib.
The Lord solemnly promised your ancestors to give you the land of the Canaanites, the Hittites, the Amorites, the Hivites, and the Jebusites. When he brings you into that rich and fertile land, you must celebrate this festival in the first month of every year.
For seven days you must eat unleavened bread and on the seventh day there is to be a festival to honor the Lord.
For seven days you must not eat any bread made with yeast; there must be no yeast or leavened bread anywhere in your land.
When the festival begins, explain to your sons that you do all this because of what the Lord did for you when you left Egypt.
