'Behalf' in the Bible

“If I alone testify about Myself, My testimony is not valid.

There is another [My Father] who testifies about Me, and I know [without any doubt] that His testimony on My behalf is true and valid.

But the testimony I receive is not from man [a merely human witness]; but I say these things so that you may be saved [that is, have eternal life].

Then the Pharisees told Him, “You are testifying on Your own behalf; Your testimony is not valid.”

Jesus replied, “Even if I do testify on My own behalf, My testimony is valid, because I know where I came from and where I am going; but you do not know where I come from or where I am going.

even as the Father knows Me and I know the Father—and I lay down My [very own] life [sacrificing it] for the benefit of the sheep.

Nor do you understand that it is expedient and politically advantageous for you that one man die for the people, and that the whole nation not perish.”

But the Helper (Comforter, Advocate, Intercessor—Counselor, Strengthener, Standby), the Holy Spirit, whom the Father will send in My name [in My place, to represent Me and act on My behalf], He will teach you all things. And He will help you remember everything that I have told you.

In that day you will ask in My name, and I am not saying to you that I will ask the Father on your behalf [because it will be unnecessary];

For their sake I sanctify Myself [to do Your will], so that they also may be sanctified [set apart, dedicated, made holy] in [Your] truth.

It was Caiaphas who had advised the Jews that it was expedient for one man to die on behalf of the people.
