Thematic Bible: Observed at the place designated by God

"You must not sacrifice the Passover in just any of your cities that the LORD your God is about to give you. But at the place where your God will choose to establish his name, you are to sacrifice the Passover in the evening at dusk, at the time of day you left Egypt. Boil and eat the Passover meal at the place that the LORD your God will choose. In the morning you may go back to your tents.
