Deuteronomy 16:3-5

New International Reader's Version

³ Don’t eat the animal along with bread made with yeast. Instead, for seven days eat bread made without yeast. It’s the bread that reminds you of how much you suffered. Remember that you left Egypt in a hurry. Remember it all the days of your life. Don’t forget the day you left Egypt. ⁴ Don’t keep any yeast anywhere in your land for seven days. You will sacrifice the Passover animal on the evening of the first day. Do not let any of its meat be left over until the next morning.

⁵ You must not sacrifice the Passover animal in just any town the Lord your God is giving you.
