18 Now in the morning as he returned into the city, he hungered.19 And when he saw a fig tree in the way, he came to it, and found nothing thereon, but leaves only, and said unto it, Let no fruit grow on thee henceforward for ever. And presently the fig tree withered away.20 And when the disciples saw it, they marvelled, saying, How soon is the fig tree withered away!21 Jesus 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.22 And all things, whatsoever ye shall ask in prayer, believing, ye shall receive.23 And 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?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.28 But what think ye? A certain man had two sons; and he came to the first, and said, Son, go work to day in my vineyard.
