'Man of God' in the Bible
And he appointed, according to the order of David his father, the courses of the priests to their service, and the Levites to their charges, to praise and minister before the priests, as the duty of every day required: the porters also by their courses at every gate: for so had David the man of God commanded.
But the word of the LORD came to Shemaiah the man of God, saying,
But there came a man of God to him, saying, O king, let not the army of Israel go with thee; for the LORD is not with Israel, to wit, with all the children of Ephraim.
And Amaziah said to the man of God, But what shall we do for the hundred talents which I have given to the army of Israel? And the man of God answered, The LORD is able to give thee much more than this.
The man of God answered, "The LORD has a lot more than that to give you!" So Amaziah sent the troops home who had arrived from Ephraim. They flew into a rage against Judah but left for home very angry.
