KJC(i)
14 And when they had come to the multitude, there came to him a certain man, kneeling down to him, and saying,
15 Lord, have mercy on my son: for he is insane, and intensely vexed: for frequently he falls into the fire, and often into the water.
16 And I brought him to your disciples, and they could not cure him.
17 Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I endure you? bring him to here to me.
18 And Jesus rebuked the devil; and he departed out of him: and the child was cured from that very hour.
19 Then came the disciples to Jesus apart, and said, Why could not we cast him out?
20 And Jesus said unto them, Because of your unbelief: for truthfully I say unto you, If you have faith as a grain of mustard seed, you shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.
21 But this kind goes not out except by prayer and fasting.
