Deuteronomy 16:5-7

5Thou mayest not sacrifice the passover within any of thy gates, which Jehovah thy God giveth thee;

6but at the place which Jehovah thy God shall choose, to cause his name to dwell in, there thou shalt sacrifice the passover at even, at the going down of the sun, at the season that thou camest forth out of Egypt.

7And thou shalt roast and eat it in the place which Jehovah thy God shall choose: and thou shalt turn in the morning, and go unto thy tents.
