Mark 11:27-33

²⁷And they come again to Jerusalem: and as he was walking in the temple, there come to him the chief priests, and the scribes, and the elders, ²⁸And say unto him, By what authority doest thou these things? and who gave thee this authority to do these things? ²⁹And Jesus answered and said unto them, I will also ask of you one question, and answer me, and I will tell you by what authority I do these things. ³⁰The baptism of John, was it from heaven, or of men? answer me. ³¹And they reasoned with themselves, saying, If we shall say, From heaven; he will say, Why then did ye not believe him? ³²But if we shall say, Of men; they feared the people: for all men counted John, that he was a prophet indeed. ³³And they answered and said unto Jesus, We cannot tell. And Jesus answering saith unto them, Neither do I tell you by what authority I do these things.
