Exodus 12:21–30

²¹Then Moses called for all the elders of Israel, and said unto them, Draw out and take you a lamb ^raccording to your families, and kill the passover. ²²And ye shall take a bunch of ^shyssop, and ^tdip it in the blood that is in the bason, and strike ^uthe lintel and the two side posts with the blood that is in the bason; and none of you shall go out at the door of his house until the morning. ²³For the Lord will pass through to smite the Egyptians; and when he seeth the blood upon ^uthe lintel, and on the two side posts, the Lord will pass over the door, and will not suffer the destroyer to come in unto your houses to smite you. ²⁴And ye shall observe this thing for an ordinance to thee and to thy sons for ever. ²⁵And it shall come to pass, when ye be come to the land which the Lord will give you, ^xaccording as he hath promised, that ye shall keep this service. ²⁶And it shall come to pass, ^ywhen your children shall say unto you, What mean you by this service? ²⁷that ye shall say, ^zIt is the sacrifice of the Lord’s passover, who passed over the houses of the children of Israel in Egypt, when he smote the Egyptians, and delivered our houses. And the people ^abowed the head and worshipped. ²⁸And the children of Israel went away, and did as the Lord had commanded Moses and Aaron, so did they.

²⁹And it came to pass, that ^bat midnight ^cthe Lord smote all the firstborn in the land of Egypt, ^dfrom the firstborn of Pharaoh that sat on his throne unto the firstborn of the captive that was in the dungeon; and all the firstborn of cattle. ³⁰And Pharaoh rose up in the night, he, and all his servants, and all the Egyptians; and there was a ^egreat cry in Egypt; for there was not a house where there was not one dead.
