'Authority' in the Bible

So the Jews asked Him, "What proof of your authority do you exhibit to us, seeing that you do these things?"

And He has conferred on Him authority to act as Judge, because He is the Son of Man.

Jesus therefore, while teaching in the Temple, cried aloud, and said, "Yes, you know me, and you know where I am from. And yet I have not come of my own accord; but there is One who has sent me, an Authority indeed, of whom you have no knowledge.

Because I have not spoken on my own authority; but the Father who sent me, Himself gave me a command what to say and in what words to speak.

Do you not believe that I am in the Father and that the Father is in me? The things that I tell you all I do not speak on my own authority: but the Father dwelling within me carries on His own work.

even as Thou hast given Him authority over all mankind, so that on all whom Thou hast given Him He may bestow the Life of the Ages.
