2 Chronicles 18:11-15

All the prophets were prophesying this as well, saying, “Go up to Ramoth-gilead and be successful, for the Lord will hand it over to the king.” Micaiah Brings Word from God

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

But Micaiah said, “As the Lord lives, whatever my God says, I will speak it.”

When he came to the king, the king said to him, “Micaiah, should we go to battle against Ramoth-gilead, or should I refrain?” He said, “Go up and succeed, for they will be handed over to you!”

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?”
