Exodus 12:25-33

25It will come to pass when you come to the land which the Lord will give you, just as He promised, that you shall keep this service.

26And it shall be, when your children say to you, ‘What do you mean by this service?’

27that you shall say, ‘It is the Passover sacrifice of the Lord, who passed over the houses of the children of Israel in Egypt when He struck the Egyptians and delivered our households.’ ” So the people bowed their heads and worshiped.

28Then the children of Israel went away and did so; just as the Lord had commanded Moses and Aaron, so they did.

29And it came to pass at midnight that the Lord struck 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 livestock.

30So Pharaoh rose in the night, he, all his servants, and all the Egyptians; and there was a great cry in Egypt, for there was not a house where there was not one dead.

31Then he called for Moses and Aaron by night, and said, “Rise, go out from among my people, both you and the children of Israel. And go, serve the Lord as you have said.

32Also take your flocks and your herds, as you have said, and be gone; and bless me also.”

33And the Egyptians urged the people, that they might send them out of the land in haste. For they said, “We shall all be dead.”
