Deuteronomy 16:4-6

New International Reader's Version

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. ⁶ Sacrifice it only in the special place he will choose for his Name. Sacrifice it there in the evening when the sun goes down. Do it on the same day every year. Be sure it’s the day you left Egypt.
