Origen, on Exod 12:23

“For the Lord will pass through striking the Egyptians: and when he shall see the blood on the transom, and on both the posts, he will pass over the door of the house, and not suffer the destroyer to come into your houses and to hurt you.”

“We must also inquire who that being was of whom it is said in Exodus that he wished to kill Moses because he was setting out for Egypt. And afterwards, who is it that is called the "destroying angel"? And who also is he who in Leviticus is described as Apopompeus, that is, the Averter, of whom the Scripture speaks thus: "One lot for the Lord, and one lot for Apopompeus"?”
