1 Kings 22:13-14

13And the messenger that was gone to call Micaiah spake unto him, saying, Behold now, the words of the prophets declare good unto the king with one mouth: let thy word, I pray thee, be like the word of one of them, and speak that which is good.

14And Micaiah said, As Yhwh liveth, what Yhwh saith unto me, that will I speak.
