John 8:25-29

So they were saying to Him, “Who are You?” Jesus said to them, “What have I been saying to you from the beginning? I have many things to speak and to judge concerning you, but He who sent Me is true; and the things which I heard from Him, these I speak to the world.” They did not realize that He had been speaking to them about the Father. So Jesus said, “When you lift up the Son of Man, then you will know that I am He, and I do nothing on My own initiative, but I speak these things as the Father taught Me. And He who sent Me is with Me; He has not left Me alone, for I always do the things that are pleasing to Him.”
