Matthew 21:24

21 Jesus answered and said to them, Verily I say to you, If ye have faith, and doubt not, ye shall not only do this [which is done] to the fig-tree, but also, if ye shall say to this mountain, Be thou removed, and be thou cast into the sea; it shall be done.

22 And all things whatever ye shall ask in prayer, believing, ye shall receive.

23 And 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?

24 And 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.

25 The 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 to us, Why then did ye not believe him?

26 But if we shall say, From 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 to them, Neither do I tell you by what authority I do these things.
