Observe the month of Abib, and keep the passover unto the LORD your God: for in the month of Abib the LORD your God brought you forth out of Egypt by night.
The feast of unleavened bread shall you keep. Seven days you shall eat unleavened bread, as I commanded you, in the time of the month Abib: for in the month Abib you came out from Egypt.
This month shall be unto you the beginning of months: it shall be the first month of the year to you.
And it came to pass, that at midnight the LORD smote all the firstborn in the land of Egypt, from the firstborn of Pharaoh that sat on his throne to the firstborn of the captive that was in the dungeon; and all the firstborn of cattle.
You shall keep the feast of unleavened bread: (you shall eat unleavened bread seven days, as I commanded you, in the time appointed of the month Abib; for in it you came out from Egypt: and none shall appear before me empty:)
Let the children of Israel also keep the passover at its appointed time.
