Judges 13:15-20

And Manoah said to the Angel of the Lord, Pray, let us detain you that we may prepare a kid for you. And the Angel of the Lord said to Manoah, Though you detain me, I will not eat of your food, but if you make ready a burnt offering, offer it to the Lord. For Manoah did not know that he was the Angel of the Lord. And Manoah said to the Angel of the Lord, What is your name, so that when your words come true, we may do you honor? And the Angel of the Lord said to him, Why do you ask my name, seeing it is wonderful? [Isa. 9:6.] So Manoah took the kid with the cereal offering and offered it upon a rock to the Lord, the Angel working wonders, while Manoah and his wife looked on. For when the flame went up toward the heavens from the altar, the Angel of the Lord ascended in the altar flame. And Manoah and his wife looked on, and they fell on their faces to the ground.
