Judges 13:20-22

20And it came to pass, as the flame went up from off the altar towards the heavens, that the Angel of Jehovah ascended in the flame of the altar; and Manoah and his wife looked on, and fell on their faces to the ground.

21And the Angel of Jehovah appeared no more to Manoah and to his wife. Then Manoah knew that it was the Angel of Jehovah.

22And Manoah said to his wife, We shall surely die, because we have seen 1God.
