Êxodo 12:23

23 When the Lord goes through the land to strike down the Egyptians, he will see the blood on the top and sides of the doorframe and will pass over that doorway, and he will not permit the destroyer to enter your houses and strike you down.

23 For the Lord will go through the land, sending death on the Egyptians; and when he sees the blood on the two sides and the top of the door, the Lord will go over your door and will not let death come in for your destruction.
