Matthew 21:18

15 And when the chief priests and the scribes saw the wonders which he wrought, and the children crying in the temple and saying, Hosanna to the Son of David, they were indignant,

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

17 And leaving them he went forth out of the city to Bethany, and there he passed the night.

18 But early in the morning, as he came back into the city, he hungered.

19 And seeing one fig-tree in the way, he came to it and found on it nothing but leaves only. And he says to it, Let there be never more fruit of thee for ever. And the fig-tree was immediately dried up.

20 And when the disciples saw [it], they wondered, saying, How immediately is the fig-tree dried up!

21 And Jesus answering said to them, Verily I say unto you, If ye have faith, and do not doubt, not only shall ye do what [is done] to the fig-tree, but even if ye should say to this mountain, Be thou taken away and be thou cast into the sea, it shall come to pass.
