Matthew 21:14-22

And the blind and the lame came to Him in the porches and courts of the temple, and He cured them. But when the chief priests and the scribes saw the wonderful things that He did and the boys and the girls and the youths and the maidens crying out in the porches and courts of the temple, Hosanna (O be propitious, graciously inclined) to the Son of David! they were indignant. And they said to Him, Do You hear what these are saying? And Jesus replied to them, Yes; have you never read, Out of the mouths of babes and unweaned infants You have made (provided) perfect praise? [Ps. 8:2.] And leaving them, He departed from the city and went out to Bethany and lodged there. In the early dawn the next morning, as He was coming back to the city, He was hungry. And as He saw one single leafy fig tree above the roadside, He went to it but He found nothing but leaves on it [seeing that in the fig tree the fruit appears at the same time as the leaves]. And He said to it, Never again shall fruit grow on you! And the fig tree withered up at once. When the disciples saw it, they marveled greatly and asked, How is it that the fig tree has withered away all at once? And Jesus answered them, Truly I say to you, if you have faith (a firm relying trust) and do not doubt, you will not only do what has been done to the fig tree, but even if you say to this mountain, Be taken up and cast into the sea, it will be done. And whatever you ask for in prayer, having faith and [really] believing, you will receive.
