Matthew 21:18-22

21:18 Now in the morning as he returned into the city, he hungered.

21:19 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.

21:20 And when the disciples saw it, they marvelled, saying, 
How soon is the fig tree withered away! 

21:21 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.

21:22 And all things, whatsoever ye shall ask in prayer, believing, ye shall receive.

Mark 11:11-14, 20-26

11:11 And Jesus entered into Jerusalem, and into the temple: 
and when he had looked round about upon all things, 
and now the eventide was come, he went out unto Bethany with the twelve.

11:12 And on the morrow, when they were come from Bethany, he was hungry: 

11:13 And seeing a fig tree afar off having leaves, he came, 
if haply he might find any thing thereon: and when he came to it, 
he found nothing but leaves; for the time of figs was not yet.

11:14 And Jesus answered and said unto it, 
No man eat fruit of thee hereafter for ever. 
And his disciples heard it.

...

11:20 And in the morning, as they passed by, they saw the fig tree dried up from the roots.

11:21 And Peter calling to remembrance saith unto him, 
Master, behold, the fig tree which thou cursedst is withered away.

11:22 And Jesus answering saith unto them, 
Have faith in God.

11:23 For verily I say unto you, That whosoever shall say unto this mountain, 
Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe 
that those things which he saith shall come to pass; he shall have whatsoever he saith.

11:24 Therefore I say unto you, 
What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them.

11:25 And when ye stand praying, forgive, if ye have ought against any: 
that your Father also which is in heaven may forgive you your trespasses.

11:26 But if ye do not forgive, neither will your Father which is in heaven forgive your trespasses.
