Deuteronomy 16:5-7

Don’t sacrifice the Passover in any of the towns that GOD, your God, gives you other than the one GOD, your God, designates for worship; there and there only you will offer the Passover-Sacrifice at evening as the sun goes down, marking the time that you left Egypt. Boil and eat it at the place designated by GOD, your God. Then, at daybreak, turn around and go home.
