'Man of God' in the Bible

Then the woman went and told her husband, saying, “A Man of God came to me and his appearance was like the appearance of the Angel of God, very awesome. I did not ask Him where he came from, and he did not tell me his name.

Then Manoah pleaded with the Lord and said, “O Lord, please let the Man of God whom You sent come again to us and teach us what we are to do for the boy who is to be born.”
