'By What Authority' in the Bible

and they say to him, 'By what authority dost thou these things? and who gave thee this authority that these things thou mayest do?'

And Jesus answering said to them, 'I will question you -- I also -- one word; and answer me, and I will tell you by what authority I do these things;

and answering they say to Jesus, 'We have not known;' and Jesus answering saith to them, 'Neither do I tell you by what authority I do these things.'
