Deuteronomy 16:5-8

Amplified Bible

⁵ You are not allowed to sacrifice the Passover [lamb] in any of your cities which the Lord your God is giving you; ⁶ but at the place where the Lord your God chooses to establish His Name (Presence), you shall sacrifice the Passover [lamb] in the evening at sunset, at the time that you came out of Egypt. ⁷ You shall cook and eat it in the place which the Lord your God chooses. In the morning you are to return to your tents. ⁸ For six days you shall eat unleavened bread, and on the seventh day there shall be a celebration to the Lord your God; so you shall do no work [on that day].
