'One Who Sent Me' in the Bible

Then Jesus called out as He taught in the temple, “You know Me and know where I am from; and I have not come on my own initiative [as self-appointed], but He who sent Me is true, and Him you do not know.

But they will do all these [hurtful] things to you for My name’s sake [because you bear My name and are identified with Me], for they do not know the One who sent Me.
