'Man of God' in the Bible

Then the woman went and told her husband, “A man of God came to me. He looked like the awe-inspiring Angel of God. I didn’t ask Him where He came from, and He didn’t tell me His name.

Manoah prayed to the Lord and said, “Please Lord, let the man of God you sent come again to us and teach us what we should do for the boy who will be born.”
