'He Who Sent Me' in the Bible

And I knew him not; but he who sent me to baptize in water, the same said to me, Upon whom thou shalt see the Spirit descending and abiding on him, he it is that baptizeth in the Holy Spirit.

But even if I myself should judge, my judgment is true, because I am not alone, but I and he who sent me.

I have many things to say, and to judge, concerning you; but he who sent me is true; and I speak to the world what I heard from him.
