28 Jesus therefore cried in the temple, teaching and saying, Ye both know me, and know whence I am; and I am not come of myself, but he that sent me is true, whom ye know not.
Christ proclaimed aloud, that they were in error in their thoughts about his origin. He was sent of God, who showed himself true to his promises. This declaration, that they knew not God, with his claim to peculiar knowledge, provoked the hearers; and they sought to take him, but God can tie men's hands, though he does not turn their hearts.
