'By What Authority' in the Bible

And when he had come into the temple, the chief priests and the elders of the people came to him as he was teaching, and said, By what authority doest thou these things? And who gave thee this authority?

And Jesus answering said to them, I also will ask you one question; which if ye answer me, I too will tell you by what authority I do these things.

And they answered Jesus and said, We do not know. And he said to them, Neither do I tell you by what authority I do these things.
