14And when they were come to the multitude, there came to him a man, kneeling to him, and saying, 15Lord, have mercy on my son: for he is epileptic, and suffereth grievously; for oft-times he falleth into the fire, and oft-times into the water. 16And I brought him to thy disciples, and they could not cure him. 17And Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I bear with you? bring him hither to me. 18And Jesus rebuked him; and the demon went out of him: and the boy was cured from that hour. 19Then came the disciples to Jesus apart, and said, Why could not we cast it out? 20And he saith unto them, Because of your little faith: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.

21But this kind goeth not out save by prayer and fasting.

22And while they abode in Galilee, Jesus said unto them, The Son of man shall be delivered up into the hands of men; 23and they shall kill him, and the third day he shall be raised up. And they were exceeding sorry.
