1 Kings 22:6-12
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.”
22:9 The king of Israel summoned an official and said, “Quickly bring Micaiah son of Imlah.”
22:10 Now the king of Israel and King Jehoshaphat of Judah were sitting on their respective thrones, dressed in their robes, at the threshing floor at the entrance of the gate of Samaria. All the prophets were prophesying before them.
22:11 Zedekiah son of Kenaanah made iron horns and said, “This is what the Lord says, ‘With these you will gore Syria until they are destroyed.’”
22:12 All the prophets were prophesying the same, saying, “Attack Ramoth Gilead! You will succeed; the Lord will hand it over to the king.”
