Matthew 21:18-22

¹⁸Now in the morning as he returned to the city, he hungered. ¹⁹And seeing a fig tree by the wayside, he came to it, and found nothing thereon, but leaves only; and he saith unto it, Let there be no fruit from thee henceforward forever. And immediately the fig tree withered away. ²⁰And when the disciples saw it, they marveled, saying, How did the fig tree immediately wither away? ²¹And Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do what is done to the fig tree, but even if ye shall say unto this mountain, Be thou taken up and cast into the sea, it shall be done. ²²And all things, whatsoever ye shall ask in prayer, believing, ye shall receive.
