'He Who Sent Me' in the Bible

I didn't recognize him, but he who sent me to baptize in water, he said to me, 'On whomever you will see the Spirit descending, and remaining on him, the same is he who baptizes in the Holy Spirit.'

Jesus therefore cried out in the temple, teaching and saying, "You both know me, and know where I am from. I have not come of myself, but he who sent me is true, whom you don't know.

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

He who sent me is with me. The Father hasn't left me alone, for I always do the things that are pleasing to him."
