'By What Authority' in the Bible

And the chief priests and elders of the people came to Him, while teaching, He having come into the temple, saying, By what authority are you doing these things? And who gave you this authority?

And Jesus responding, said to them, I ask you also one word, which if you may speak to me, I also will tell you by what authority I am doing these things:

And responding they said to Jesus, We do not know. He also said to them, Neither do I tell you by what authority I am doing these things.
