Deuteronomy 16:2-6

2Slaughter an animal from your flock or herd as the Passover sacrifice to the Lord your God. Do this at the place where the Lord will choose for his name to live.

3Never eat leavened bread with the meat from this sacrifice. Instead, for seven days you must eat unleavened bread at this festival. (It is the bread of misery because you left Egypt in a hurry.) Eat this bread so that, as long as you live, you will remember the day you left Egypt.

4There should be no yeast anywhere in your land for seven days. Never leave until morning any of the meat you slaughter on the evening of the first day.

5You’re not allowed to slaughter the animals for Passover in any of the cities the Lord your God is giving you.

6Instead, slaughter your animals for Passover in the place where the Lord your God will choose for his name to live. Do this in the evening as the sun goes down. This is the same time you did it when you left Egypt.
