Moses said, "Thus says the LORD, 'About midnight I am going out into the midst of Egypt, and all the firstborn in the land of Egypt shall die, from the firstborn of the Pharaoh who sits on his throne, even to the firstborn of the slave girl who is behind the millstones; all the firstborn of the cattle as well."
Could someone tell me how this works? We understand that there is sin, but why the firstborn (have they done something wrong?)
Someone asked me this question and I could not answer it.
