Deuteronomy 16:5-7

5You may not offer the Passover sacrifice within any of your towns that the Lord your God is giving you,

6but at the place that the Lord your God will choose, to make his name dwell in it, there you shall offer the Passover sacrifice, in the evening at sunset, at the time you came out of Egypt.

7And you shall cook it and eat it at the place that the Lord your God will choose. And in the morning you shall turn and go to your tents.
