Judges 13:20-23

For it came to pass, when the flame went up toward heaven from off the altar, that the angel of Jehovah ascended in the flame of the altar: and Manoah and his wife looked on; and they fell on their faces to the ground. But the angel of Jehovah did no more appear to Manoah or to his wife. Then Manoah knew that he was the angel of Jehovah. And Manoah said unto his wife, We shall surely die, because we have seen God. But his wife said unto him, If Jehovah were pleased to kill us, he would not have received a burnt-offering and a meal-offering at our hand, neither would he have showed us all these things, nor would at this time have told such things as these.
