1 Kings 22:6, 13

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

And the messenger who went to summon Micaiah said to him, “Behold, the words of the prophets with one accord are favorable to the king. Let your word be like the word of one of them, and speak favorably.”
