Matthew 21:18

15 And when the chief priests and scribes saw the wonderful things that he did, and the children crying in the temple, and saying, Hosanna to the son of David; they were greatly displeased,

16 And said to him, Hearest thou what these say? And Jesus saith to them, Yes: have ye never read, Out of the mouth of babes and sucklings thou hast perfected praise?

17 And he left them, and went out of the city into Bethany, and he lodged there.

18 Now in the morning as he was returning into the city, he was hungry.

19 And when he saw a fig-tree in the way, he came to it, and found nothing on it, but leaves only, and said to it, Let no fruit grow on thee henceforth for ever. And immediately the fig-tree withered.

20 And when the disciples saw [it], they marveled, saying, How soon is the fig-tree withered!

21 Jesus answered and said to them, Verily I say to you, If ye have faith, and doubt not, ye shall not only do this [which is done] to the fig-tree, but also, if ye shall say to this mountain, Be thou removed, and be thou cast into the sea; it shall be done.
