Matthew 17:14-21

17:14 And when they were come to the multitude, there came to him a certain man, 
kneeling down to him, and saying, 

17:15 Lord, have mercy on my son: for he is lunatick, and sore vexed: 
for ofttimes he falleth into the fire, and oft into the water.

17:16 And I brought him to thy disciples, and they could not cure him.

17:17 Then Jesus answered and said, 
O faithless and perverse generation, how long shall I be with you? 
how long shall I suffer you? bring him hither to me.

17:18 And Jesus rebuked the devil; and he departed out of him: 
and the child was cured from that very hour.

17:19 Then came the disciples to Jesus apart, and said, 
Why could not we cast him out? 

17:20 And Jesus said unto them, 
Because of your unbelief: 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.

17:21 Howbeit this kind goeth not out but by prayer and fasting.

Mark 9:14-29

9:14 And when he came to his disciples, he saw a great multitude about them, 
and the scribes questioning with them.

9:15 And straightway all the people, when they beheld him, 
were greatly amazed, and running to him saluted him.

9:16 And he asked the scribes, What question ye with them? 

9:17 And one of the multitude answered and said, 
Master, I have brought unto thee my son, which hath a dumb spirit; 

9:18 And wheresoever he taketh him, he teareth him: 
and he foameth, and gnasheth with his teeth, and pineth away: 
and I spake to thy disciples that they should cast him out; and they could not.

9:19 He answereth him, and saith, 
O faithless generation, how long shall I be with you? 
how long shall I suffer you? bring him unto me.

9:20 And they brought him unto him: 
and when he saw him, straightway the spirit tare him; 
and he fell on the ground, and wallowed foaming.

9:21 And he asked his father, How long is it ago since this came unto him? 
And he said, Of a child.

9:22 And ofttimes it hath cast him into the fire, and into the waters, 
to destroy him: but if thou canst do any thing, have compassion on us, and help us.

9:23 Jesus said unto him, 
If thou canst believe, all things are possible to him that believeth.

9:24 And straightway the father of the child cried out, and said 
with tears, Lord, I believe; help thou mine unbelief.

9:25 When Jesus saw that the people came running together, he rebuked the foul spirit, saying unto him, 
Thou dumb and deaf spirit, I charge thee, come out of him, and enter no more into him.

9:26 And the spirit cried, and rent him sore, and came out of him: 
and he was as one dead; insomuch that many said, He is dead.

9:27 But Jesus took him by the hand, and lifted him up; and he arose.

9:28 And when he was come into the house, his disciples asked him privately, 
Why could not we cast him out? 

9:29 And he said unto them, 
This kind can come forth by nothing, but by prayer and fasting.

Luke 9:37-43

9:37 And it came to pass, that on the next day, 
when they were come down from the hill, much people met him.

9:38 And, behold, a man of the company cried out, saying, 
Master, I beseech thee, look upon my son: for he is mine only child.

9:39 And, lo, a spirit taketh him, and he suddenly crieth out; 
and it teareth him that he foameth again, and bruising him hardly departeth from him.

9:40 And I besought thy disciples to cast him out; and they could not.

9:41 And Jesus answering said, 
O faithless and perverse generation, how long shall I be with you, and suffer you? Bring thy son hither.

9:42 And as he was yet a coming, the devil threw him down, and tare him. 
And Jesus rebuked the unclean spirit, and healed the child, and delivered him again to his father.

9:43 And they were all amazed at the mighty power of God. 
But while they wondered every one at all things which Jesus did, he said unto his disciples,
