1 Kings 22:5-8

Jehoshaphat also said to Ahab, “But first we should ask if this is the LORD’s will.” Ahab called about four hundred prophets together and asked them, “Should I go to war against Ramoth in Gilead or not?” They answered, “Go, because the Lord will hand them over to you.” But Jehoshaphat asked, “Isn’t there a prophet of the LORD here? Let’s ask him what we should do.” Then King Ahab said to Jehoshaphat, “There is one other prophet. We could ask the LORD through him, but I hate him. He never prophesies anything good about me, but something bad. He is Micaiah son of Imlah.” Jehoshaphat said, “King Ahab, you shouldn’t say that!”
