'He Who Sent Me' in the Bible

I did not recognize Him [as the Messiah], but He who sent me to baptize in water said to me, ‘He upon whom you see the Spirit descend and remain, this One is He who baptizes with the Holy Spirit.’

I have many things to say and judge concerning you, but He who sent Me is true; and I say to the world [only] the things that I have heard from Him.”

And He who sent Me is [always] with Me; He has not left Me alone, because I always do what pleases Him.”
