Deuteronomy 16:5-7

5You must not kill the animal for the Passover sacrifice in any of the towns that the Lord your God gives to you.

6You must go to the place that he will choose as his special home. You must kill the animal there, at sunset. That was the time of day when you came out of Egypt.

7Cook the meat and eat it in the place that the Lord your God will choose. The next morning, you may return to your tents.
