Exodus 12:29, 33, 42, 51

At midnight the LORD struck down all the firstborn in the land of Egypt, from the firstborn of Pharaoh who sat on his throne to the firstborn of the captive who was in the dungeon, and all the firstborn of the livestock.

The Egyptians were urgent with the people to send them out of the land in haste. For they said, “We shall all be dead.”

It was a night of watching by the LORD, to bring them out of the land of Egypt; so this same night is a night of watching kept to the LORD by all the people of Israel throughout their generations.

And on that very day the LORD brought the people of Israel out of the land of Egypt by their hosts.
