'Man of God' in the Bible

And the heads of the Levites: Hashabiah, Sherebiah, and Joshua son of Kadmiel, and their brethren over against them, to praise, to confess in the command of David the man of God watching over against watching.

And his brethren, Shemaiah, and Azarael, Milalai, Gilalai, Maai, Nathaneel, and Judah, Hanani, with instruments of song of David the man of God, and Ezra the scribe before them.
