Deuteronomy 16:2, 6

And you shall offer the Passover sacrifice to the LORD your God, from the flock or the herd, at the place that the LORD will choose, to make his name dwell there.

but at the place that the LORD your God will choose, to make his name dwell in it, there you shall offer the Passover sacrifice, in the evening at sunset, at the time you came out of Egypt.
