John Gill Commentary 1 Kings 22:7

"But Jehoshaphat said, Is there not here a prophet of Jehovah besides, that we may inquire of him?" — 1 Kings 22:7 (ASV)

And Jehoshaphat said, is there not here a prophet of the Lord
besides, that we might inquire of him ?
] He suspected these to be false prophets, though he would not call them so; nor suggest that they were not the prophets of the Lord, because he would not affront Ahab, who had an opinion of them; and therefore asks, if there were no other that went under the character of a prophet of the Lord, that he might inquire of him for his further satisfaction.
