Jeremiah 38:15

Then Jeremiah said unto Zedekiah, If I declare it unto thee, telling him the plain truth as it had been revealed by the Lord, wilt thou not surely put me to death? And if I give thee counsel, namely, concerning the manner in which he was to proceed in this emergency, wilt thou not hearken unto me? It is plain that Jeremiah trusted the king neither with regard to the safety of his own person nor concerning the acceptance of any advice which he might give.
