1 Kings 22:3-8
22:3 The king of Israel said to his servants, “Surely you recognize that Ramoth Gilead belongs to us, though we are hesitant to reclaim it from the king of Syria.”
22:4 Then he said to Jehoshaphat, “Will you go with me to attack Ramoth Gilead?” Jehoshaphat replied to the king of Israel, “I will support you; my army and horses are at your disposal.”
22:5 Then Jehoshaphat added, “First seek an oracle from the Lord.”
22:6 So the king of Israel assembled about four hundred prophets and asked them, “Should I attack Ramoth Gilead or not?” They said, “Attack! The sovereign one will hand it over to the king.”
22:7 But Jehoshaphat asked, “Is there not a prophet of the Lord still here, that we may ask him?”
22:8 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 disaster. His name is Micaiah son of Imlah. Jehoshaphat said, “The king should not say such things.”
