1 Kings 22:4-8

He turned to Jehoshaphat and said, “Will you join me in fighting for Ramoth Gilead?” Jehoshaphat said, “You bet. I’m with you all the way—my troops are your troops, my horses are your horses.” He then continued, “But before you do anything, ask GOD for guidance.” The king of Israel got the prophets together—all four hundred of them—and put the question to them: “Should I attack Ramoth Gilead? Or should I hold back?” “Go for it,” they said. “GOD will hand it over to the king.” But Jehoshaphat dragged his heels: “Is there still another prophet of GOD around here we can consult?” The king of Israel told Jehoshaphat, “As a matter of fact, there is still one such man. But I hate him. He never preaches anything good to me, only doom, doom, doom—Micaiah son of Imlah.” “The king shouldn’t talk about a prophet like that,” said Jehoshaphat.
