1 Kings 22:12-16

All the prophets were prophesying this as well, saying, “Go up to Ramoth-gilead and succeed, for the Lord will hand it over to the king.” Micaiah Predicts Defeat

Then the messenger who went to summon Micaiah spoke to him saying, “Behold now, the words of the prophets are unanimously favorable to the king. Please let your word be like the word of one of them, and speak favorably.”

But Micaiah said, “As the Lord lives, whatever the Lord says to me, I shall speak it.”

When he came to the king, the king said to him, “Micaiah, should we go to battle against Ramoth-gilead, or should we refrain?” And he said, “Go up and succeed, for the Lord will hand it over to the king!”

Then the king said to him, “How many times must I make you swear that you will tell me nothing but the truth in the name of the Lord?”
