25 Now some of the people of Jerusalem were saying, "Is not this the man whom they are trying to kill? 26 And here he is, speaking openly, but they say nothing to him! Can it be that the authorities really know that this is the Messiah? 27 Yet we know where this man is from; but when the Messiah comes, no one will know where he is from." 28 Then Jesus cried out as he was teaching in the temple, "You know me, and you know where I am from. I have not come on my own. But the one who sent me is true, and you do not know him. 29 I know him, because I am from him, and he sent me." 30 Then they tried to arrest him, but no one laid hands on him, because his hour had not yet 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.
