I Kings 22:6, 13

Then the king of Israel gathered the prophets together, about four hundred men, and said to them, “Shall I go against Ramoth Gilead to fight, or shall I refrain?” So they said, “Go up, for the Lord will deliver it into the hand of the king.”

Then the messenger who had gone to call Micaiah spoke to him, saying, “Now listen, the words of the prophets with one accord encourage the king. Please, let your word be like the word of one of them, and speak encouragement.”
