2 Chronicles 18:5-7

So the king of Israel brought together the prophets—four hundred men—and asked them, “Shall we go to war against Ramoth Gilead, or shall I not?” “Go,” they answered, “for God will give it into the king’s hand.” But Jehoshaphat asked, “Is there no longer a prophet of the LORD here whom we can inquire of?” The king of Israel answered Jehoshaphat, “There is still one prophet through whom we can inquire of the LORD, but I hate him because he never prophesies anything good about me, but always bad. He is Micaiah son of Imlah.” “The king should not say such a thing,” Jehoshaphat replied.
