Deuteronomy 16:3-5

New Living Translation

³ Eat it with bread made without yeast. For seven days the bread you eat must be made without yeast, as when you escaped from Egypt in such a hurry. Eat this bread—the bread of suffering—so that as long as you live you will remember the day you departed from Egypt. ⁴ Let no yeast be found in any house throughout your land for those seven days. And when you sacrifice the Passover lamb on the evening of the first day, do not let any of the meat remain until the next morning.

⁵ “You may not sacrifice the Passover in just any of the towns that the Lord your God is giving you.
