Matthew 21:24-27King James Version (KJV)
24 And Jesus answered and said unto them, I also will ask you one thing, which if ye tell me, I in like wise will tell you by what authority I do these things.
25 The baptism of John, whence was it? from heaven, or of men? And they reasoned with themselves, saying, If we shall say, From heaven; he will say unto us, Why did ye not then believe him?
26 But if we shall say, Of men; we fear the people; for all hold John as a prophet.
27 And they answered Jesus, and said, We cannot tell. And he said unto them, Neither tell I you by what authority I do these things.
