Matthew 21:18-22

18In the morning, as he was returning to the city, he became hungry.

19And seeing a fig tree by the wayside, he went to it and found nothing on it but only leaves. And he said to it, "May no fruit ever come from you again!" And the fig tree withered at once.

20When the disciples saw it, they marveled, saying, "How did the fig tree wither at once?"

21And Jesus answered them, "Truly, I say to you, if you have faith 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 thrown into the sea,' it will happen.

22And whatever you ask in prayer, you will receive, if you have faith."
