Matthew 21:18-22

Now in the morning, when He was returning to the city, He became hungry. Seeing a lone fig tree by the road, He came to it and found nothing on it except leaves only; and He said to it, “No longer shall there ever be any fruit from you.” And at once the fig tree withered.

Seeing this, the disciples were amazed and asked, “How did the fig tree wither all at once?” And Jesus answered and said to them, “Truly I say to you, if you have faith and do not doubt, you will not only do what was done to the fig tree, but even if you say to this mountain, ‘Be taken up and cast into the sea,’ it will happen. And all things you ask in prayer, believing, you will receive.”

Mark 11:12-14, 20-25

On the next day, when they had left Bethany, He became hungry. Seeing at a distance a fig tree in leaf, He went to see if perhaps He would find anything on it; and when He came to it, He found nothing but leaves, for it was not the season for figs. He said to it, “May no one ever eat fruit from you again!” And His disciples were listening.

As they were passing by in the morning, they saw the fig tree withered from the roots up. Being reminded, Peter *said to Him, “Rabbi, look, the fig tree which You cursed has withered.” And Jesus *answered saying to them, “Have faith in God. Truly I say to you, whoever says to this mountain, ‘Be taken up and cast into the sea,’ and does not doubt in his heart, but believes that what he says is going to happen, it will be granted him. Therefore I say to you, all things for which you pray and ask, believe that you have received them, and they will be granted you. Whenever you stand praying, forgive, if you have anything against anyone, so that your Father who is in heaven will also forgive you your transgressions.
