Matthew 21:23-27

23And 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? 24And Jesus answered and said to them, I also will ask you one thing, which if ye tell me, I also will tell you by what authority I do these things. 25The baptism of John, where was it from? from heaven, or from men? And they reasoned with themselves, saying, If we shall say, From heaven; he will say to us, Why then did ye not believe him? 26But if we shall say, From men; we fear the people; for all hold John as a prophet. 27And they answered Jesus, and said, We cannot tell. And he said to them, Neither do I tell you by what authority I do these things.
