Judges 13:20-22

Amplified Bible

²⁰ For when the flame went up toward heaven from the altar, the Angel of the Lord ascended in the altar flame. When Manoah and his wife saw this they fell on their faces to the ground.

²¹ The Angel of the Lord did not appear again to Manoah or his wife. Then Manoah knew that he was the Angel of the Lord. ²² So Manoah said to his wife, “We will certainly die, because we have seen God.”
