Deuteronomy 16:4-6

New American Standard Bible

⁴ For seven days no leaven shall be seen with you in your entire territory, and ^(A)none of the meat which you sacrifice on the evening of the first day shall be left overnight until the morning. ⁵ You are not allowed to sacrifice the Passover in any of your ^[a]towns which the Lord your God is giving you; ⁶ but only ^(B)at the place where the Lord your God chooses to establish His name, you shall sacrifice the Passover in the evening at sunset, at the time that you came out of Egypt.
