Matthew 21:24-27

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