1 Kings 22:5-8

But Jehoshaphat said to the king of Israel, “Please inquire first for the word of the LORD.” Then the king of Israel gathered the prophets together, about four hundred men, and said to them, “Shall I go to battle against Ramoth-gilead, or should I not?” And they said, “Go up, for the LORD has handed it over to the king.” But Jehoshaphat [doubted and] said, “Is there not another prophet of the LORD here whom we may ask?” The king of Israel said to Jehoshaphat, “There is one more man, Micaiah the son of Imlah, by whom we may inquire of the LORD, but I hate him, because he never prophesies good news for me, but only evil.” But Jehoshaphat said, “May the king not say that [Micaiah only tells bad news].”
