Matthew 21:17-22 NIV
And he left them and went out of the city to Bethany, where he spent the night.
Early in the morning, as Jesus was on his way back to the city, he was hungry. Seeing a fig tree by the road, he went up to it but found nothing on it except leaves. Then he said to it, “May you never bear fruit again!” Immediately the tree withered.
When the disciples saw this, they were amazed. “How did the fig tree wither so quickly?” they asked.
Jesus replied, “Truly I tell you, if you have faith and do not doubt, not only can you do what was done to the fig tree, but also you can say to this mountain, ‘Go, throw yourself into the sea,’ and it will be done. If you believe, you will receive whatever you ask for in prayer.”
