Matthew 21:18–22

And in the morning, returning into the city, he was hungry. 19And seeing a certain fig tree by the way side, he came to it and found nothing on it but leaves only. And he saith to it: May no fruit grow on thee henceforward for ever. And immediately the fig tree withered away. 20And the disciples seeing it wondered, saying: How is it presently withered away? 21And Jesus answering, said to them: Amen, I say to you, if you shall have faith and stagger not, not only this of the fig tree shall you do, but also if you shall say to this mountain, Take up and cast thyself into the sea, it shall be done. 22And all things whatsoever you shall ask in prayer believing, you shall receive.
