Exodus 12:12-13

Holman Christian Standard Bible

¹² “I will pass through^(A) the land of Egypt on that night and strike every firstborn male in the land of Egypt, both man and beast. I am Yahweh; I will execute judgments against all the gods of Egypt.^{(B) 13} The blood on the houses where you are staying will be a distinguishing mark for you; when I see the blood, I will pass over you. No plague will be among you to destroy you when I strike the land of Egypt.
