Judges 13:18

15 And Manoah said to the angel of the Lord, Now let us keep you while we make ready a young goat for you.

16 And the angel of the Lord said to Manoah, Though you keep me I will not take of your food; but if you will make a burned offering, let it be offered to the Lord. For it had not come into Manoah's mind that he was the angel of the Lord.

17 Then Manoah said to the angel of the Lord, What is your name, so that when your words come true we may give you honour?

18 But the angel of the Lord said to him, Why are you questioning me about my name, seeing that it is a wonder?

19 So Manoah took the young goat with its meal offering, offering it on the rock to the Lord, who did strange things.

20 And when the flame went up to heaven from the altar, the angel of the Lord went up in the flame of the altar, while Manoah and his wife were looking on; and they went down on their faces to the earth.

21 But the angel of the Lord was seen no more by Manoah and his wife. Then it was clear to Manoah that he was the angel of the Lord.
