Deuteronomy 16:4-6

Common English Bible

⁴ No dough with yeast should appear in any of your territory for seven days. Furthermore, none of the meat that you sacrificed on the first night should remain until morning. ⁵ You are not permitted to offer the Passover sacrifice in any of the cities that the Lord your God is giving you. ⁶ Instead, you must offer the Passover sacrifice at the location the Lord your God selects for his name to reside, at evening time, when the sun sets, which was the time you fled Egypt.
