'Passover' in the Bible

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

Thou shalt therefore sacrifice the passover unto the LORD thy God, of the flock and the herd, in the place which the LORD shall choose to place his name there.

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

But at the place which the LORD thy God shall choose to place his name 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.

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.
