Deuteronomy 16:3-5

International Children’s Bible

³ Do not eat it with bread made with yeast. But for seven days eat bread made without yeast. This is the bread of suffering because you left Egypt in a hurry. So all your life you will remember the time you left Egypt. ⁴ There must be no yeast anywhere in your land for seven days. Offer the sacrifice on the evening of the first day. Eat all the meat before morning. Do not leave it overnight.

⁵ Do not offer the Passover sacrifice in just any town the Lord your God gives you.
