'Passover' in the Bible

Observe the month of Abib, and keep the Passover to Yahweh your God; for in the month of Abib Yahweh your God brought you forth out of Egypt by night.

You shall sacrifice the Passover to Yahweh your God, of the flock and the herd, in the place which Yahweh shall choose, to cause his name to dwell there.

You may not sacrifice the Passover within any of your gates, which Yahweh your God gives you;

but at the place which Yahweh your God shall choose, to cause his name to dwell in, there you shall sacrifice the Passover at evening, at the going down of the sun, at the season that you came forth out of Egypt.
