Divrey Hayamim Bais 18:7

And the Melech Yisroel said unto Yehoshaphat, There is yet ish echad (one man), by whom we may inquire of HASHEM, but I hate him because he never prophesied for tov about me, but always ra'ah; the same is Mikhay'hu ben Yimlach. And Yehoshaphat said, HaMelech should not say that.
