15and saying, `Sir, deal kindly with my son, for he is lunatic, and doth suffer miserably, for often he doth fall into the fire, and often into the water,
16and I brought him near to thy disciples, and they were not able to heal him.`
17And Jesus answering said, `O generation, unstedfast and perverse, till when shall I be with you? till when shall I bear you? bring him to me hither;`
18and Jesus rebuked him, and the demon went out of him, and the lad was healed from that hour.
19Then the disciples having come to Jesus by himself, said, `Wherefore were we not able to cast him out?`
20And Jesus said to them, `Through your want of faith; for verily I say to you, if ye may have faith as a grain of mustard, ye shall say to this mount, Remove hence to yonder place, and it shall remove, and nothing shall be impossible to you,
21and this kind doth not go forth except in prayer and fasting.`
