Deuteronomy 16:5-7

5You are not to sacrifice the Passover animal in any of the towns the Lord your God is giving you.

6Sacrifice the Passover animal only at the place where the Lord your God chooses to have his name dwell. Do this in the evening as the sun sets at the same time of day you departed from Egypt.

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