21Jesus answered and said unto them, Verily I say unto 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 unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done. 22And all things, whatsoever ye shall ask in prayer, believing, ye shall receive. 23And when he was come into the temple, the chief priests and the elders of the people came unto 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 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.25The 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? 26But if we shall say, Of men; we fear the people; for all hold John as a prophet. 27And they answered Jesus, and said, We cannot tell. And he said unto them, Neither tell I you by what authority I do these things.
