John 8:25-28

25They said therefore to him, Who art thou? [And] Jesus said to them, Altogether that which I also say to you.

26I have many things to say and to judge concerning you, but he that has sent me is true, and I, what I have heard from him, these things I say to the world.

27They knew not that he spoke to them of the Father.

28Jesus therefore said to them, When ye shall have lifted up the Son of man, then ye shall know that I am [he], and [that] I do nothing of myself, but as the Father has taught me I speak these things.
