Mark 11:27-32

And 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, and say unto him, By what authority doest thou these things? and who gave thee this authority to do these things? And 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. The baptism of John, was it from heaven, or of men? answer me. And they reasoned with themselves, saying, If we shall say, From heaven; he will say, Why then did ye not believe him? But if we shall say, Of men; they feared the people: for all men counted John, that he was a prophet indeed.
