Exodus 11:5

⁵¹and struck all the firstborn in Egypt, the chief of their strength in the tents of Ham.

²⁹At midnight, 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.

³⁶He struck also all the firstborn in their land, the first fruits of all their manhood.

⁴¹Two women will be grinding at the mill: one will be taken and one will be left.

²³and I have said to you, “Let my son go, that he may serve me;” and you have refused to let him go. Behold, I will kill your firstborn son.’”

¹⁵When Pharaoh stubbornly refused to let us go, the LORD killed all the firstborn in the land of Egypt, both the firstborn of man, and the firstborn of livestock. Therefore I sacrifice to the LORD all that opens the womb, being males; but all the firstborn of my sons I redeem.’

¹²For I will go through the land of Egypt in that night, and will strike all the firstborn in the land of Egypt, both man and animal. I will execute judgments against all the gods of Egypt. I am the LORD.

¹⁰to him who struck down the Egyptian firstborn, for his loving kindness endures forever;

⁸He struck the firstborn of Egypt, both of man and animal.

²⁸By faith he kept the Passover and the sprinkling of the blood, that the destroyer of the firstborn should not touch them.
