25 Then some of the people of Jerusalem said, Is not this the man whose death is desired? 26 And here he is talking openly and they say nothing to him! Is it possible that the rulers have knowledge that this is truly the Christ? 27 However, it is clear to us where this man comes from: but when the Christ comes no one will have knowledge where he comes from. 28 Then, when he was teaching in the Temple, Jesus said with a loud voice, You have knowledge of me and you have knowledge of where I come from; and I have not come of myself; but there is One who has sent me; he is true, but you have no knowledge of him. 29 I have knowledge of him because I came from him and he sent me. 30 Then they had a desire to take him: but no man put hands on him because his hour was still to come.

Commentary on John 7:25-30
(Read John 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.
