7:28 {12} Then cried Jesus in the temple as he taught, saying, Ye both know me, and ye know whence I am: and I am not come of myself, but he that sent me is true, whom ye know not.
(12) The truth of Christ does not depend upon the judgment of man.
7:28 Ye know whence I am. This is a reply to their assertion that they did. If they really did they would know that he came from God. They did not even know God, or they would know him whom God sent.
7:28 Then cried Jesus - With a loud and earnest voice. Do ye both know me, and know whence I am ? - Ye do indeed know whence I am as a man. But ye know not my Divine nature, nor that I am sent from God.
7:25-30 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.
