1 Kings 22:13-14

13The man who had gone to fetch Micaiah said to him, ‘All the other prophets are saying the same thing. They say that the king will win the fight. So you must agree with what they are saying. Promise that something good will happen.’

14But Micaiah said, ‘I can only speak what the Lord tells me to say. As surely as the Lord lives, that is what I must do.’
