2 Chronicles 18:12-17
12 The messenger who had gone to summon Micaiah said to him, “Look, as one man the other prophets are predicting success for the king. Let your word agree with theirs, and speak favorably.”
13 But Micaiah said, “As surely as the Lord lives, I can tell him only what my God says.”
14
When he arrived, the king asked him, “Micaiah, shall we go to war against Ramoth Gilead, or shall I refrain?”
“Attack and be victorious,” he answered, “for they will be given into your hand.”
15 The king said to him, “How many times must I make you swear to tell me nothing but the truth in the name of the Lord?”
16 Then Micaiah answered, “I saw all Israel scattered on the hills like sheep without a shepherd, and the Lord said, ‘These people have no master. Let each one go home in peace.’”
17 The king of Israel said to Jehoshaphat, “Didn’t I tell you that he never prophesies anything good about me, but only bad?”
