2 Chronicles 18:4-8
18:4 Then Jehoshaphat added, “First seek an oracle from the Lord.”
18:5 So the king of Israel assembled 400 prophets and asked them, “Should we attack Ramoth Gilead or not?” They said, “Attack! God will hand it over to the king.”
18:6 But Jehoshaphat asked, “Is there not a prophet of the Lord still here, that we may ask him?”
18:7 The king of Israel answered Jehoshaphat, “There is still one man through whom we can seek the Lord’s will. But I despise him because he does not prophesy prosperity for me, but always disaster. His name is Micaiah son of Imlah. Jehoshaphat said, “The king should not say such things!”
18:8 The king of Israel summoned an officer and said, “Quickly bring Micaiah son of Imlah.”
