Exodus 12:29

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

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.’”

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

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

⁴Moses said, “This is what the LORD says: ‘About midnight I will go out into the middle of Egypt, ⁵and all the firstborn in the land of Egypt shall die, from the firstborn of Pharaoh who sits on his throne, even to the firstborn of the female servant who is behind the mill, and all the firstborn of livestock.

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

¹⁷For all the firstborn among the children of Israel are mine, both man and animal. On the day that I struck all the firstborn in the land of Egypt, I sanctified them for myself.

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.

⁴while the Egyptians were burying all their firstborn, whom the LORD had struck among them. The LORD also executed judgments on their gods.

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