1 Kings 22:6-8

6So the king of Israel brought together the prophets—about four hundred men—and asked them, “Shall I go to war against Ramoth Gilead, or shall I refrain?” “Go,” they answered, “for the Lord will give it into the king’s hand.”

7But Jehoshaphat asked, “Is there no longer a prophet of the LORD here whom we can inquire of?”

8The 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.
