Matthew 21:18

15 But the chief priests and scribes were indignant when they saw the wonders He performed and the children shouting in the temple courts, “Hosanna to the Son of David!”

16 “Do you hear what these children are saying?” they asked. “Yes,” Jesus answered. “Have you never read: ‘From the mouths of children and infants You have ordained praise’?”

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

18 In the morning, as Jesus was returning to the city, He was hungry.

19 Seeing 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.

20 When 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.
