Matthew 21:17-22

17Then He left them and went out of the city to Bethany, where He spent the night.

18In the morning, as Jesus was returning to the city, He was hungry. 19Seeing a fig tree by the road, He went up to it but found nothing on it except leaves. “May you never bear fruit again!” He said. And immediately the tree withered.

20When the disciples saw this, they marveled and asked, “How did the fig tree wither so quickly?”

21“Truly I tell you,” Jesus replied, “if you have faith and do not doubt, not only will you do what was done to the fig tree, but even if you say to this mountain, ‘Be lifted up and thrown into the sea,’ it will happen. 22If you believe, you will receive whatever you ask for in prayer.”
