Judges 13:20-23

And when the flame went up toward heaven from the altar, the angel of the LORD went up in the flame of the altar. Now Manoah and his wife were watching, and they fell on their faces to the ground. The angel of the LORD appeared no more to Manoah and to his wife. Then Manoah knew that he was the angel of the LORD. And Manoah said to his wife, “We shall surely die, for we have seen God.” But his wife said to him, “If the LORD had meant to kill us, he would not have accepted a burnt offering and a grain offering at our hands, or shown us all these things, or now announced to us such things as these.”
