'Passover' in the Bible

Observe the month of Abib, and keep the passover unto Jehovah thy God; for in the month of Abib Jehovah thy God brought thee forth out of Egypt by night.

And thou shalt sacrifice the passover unto Jehovah thy God, of the flock and the herd, in the place which Jehovah shall choose, to cause his name to dwell there.

Thou mayest not sacrifice the passover within any of thy gates, which Jehovah thy God giveth thee;

but at the place which Jehovah thy God shall choose, to cause his name to dwell in, there thou shalt sacrifice the passover at even, at the going down of the sun, at the season that thou camest forth out of Egypt.
