Deuteronomy 16:5-7

5You are not allowed to sacrifice the Passover [lamb] in any of your cities which the Lord your God is giving you;

6but 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.

7You shall cook and eat it in the place which the Lord your God chooses. In the morning you are to return to your tents.
