2 Chronicles 18:12-13

And the messenger that went to call Micaiah spake to him, saying, Behold, the words of the prophets {declare} good to the king with one assent; let thy word therefore, I pray thee, be like one of theirs, and speak thou good. {with...: Heb. with one mouth} And Micaiah said, {As} the LORD liveth, even what my God saith, that will I speak.
