Matthew 21:19-22 King James Version (KJV)
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.
Matthew 21:19-22 Amplified Bible, Classic Edition (AMPC)
19 And as He saw [a]one single leafy fig tree [b]above the roadside, He went to it but He found nothing but leaves on it [[c]seeing that in the fig tree the fruit appears at the same time as the leaves]. And He said to it, Never again shall fruit grow on you! And the fig tree withered up at once.
20 When the disciples saw it, they marveled greatly and asked, How is it that the fig tree has withered away all at once?
21 And Jesus answered them, Truly I say to you, if you have faith (a [d]firm relying trust) and do not doubt, you will not only do what has been done to the fig tree, but even if you say to this mountain, Be taken up and cast into the sea, it will be done.
22 And whatever you ask for in prayer, having faith and [really] believing, you will receive.
