Deuteronomy 16:5-7

5“You may not sacrifice the Passover within any of your gates which the Lord your God gives you;

6but at the place where the Lord your God chooses to make His name abide, there you shall sacrifice the Passover at twilight, at the going down of the sun, at the time you came out of Egypt.

7And you shall roast and eat it in the place which the Lord your God chooses, and in the morning you shall turn and go to your tents.
