12 That very night I will go all through Egypt and kill every firstborn of both people and animals, and I will bring condemnation on all the gods of Egypt. I am the Lord. 13 The blood on the houses where you live will mark them out. When I see the blood, I will pass over you. No deathly plague will fall on you to destroy you when I attack Egypt.
