Mark 9:14-29 KJV

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

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

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

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

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.

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.

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.

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

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.

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

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

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.

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.

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

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

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

2 Timothy 3:16-17 KJV

16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:

17 That the man of God may be perfect, thoroughly furnished unto all good works.

John 13:21-31 KJV

21 When Jesus had thus said, he was troubled in spirit, and testified, and said, Verily, verily, I say unto you, that one of you shall betray me.

22 Then the disciples looked one on another, doubting of whom he spake.

23 Now there was leaning on Jesus' bosom one of his disciples, whom Jesus loved.

24 Simon Peter therefore beckoned to him, that he should ask who it should be of whom he spake.

25 He then lying on Jesus' breast saith unto him, Lord, who is it?

26 Jesus answered, He it is, to whom I shall give a sop, when I have dipped it. And when he had dipped the sop, he gave it to Judas Iscariot, the son of Simon.

27 And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly.

28 Now no man at the table knew for what intent he spake this unto him.

29 For some of them thought, because Judas had the bag, that Jesus had said unto him, Buy those things that we have need of against the feast; or, that he should give something to the poor.

30 He then having received the sop went immediately out: and it was night.

31 Therefore, when he was gone out, Jesus said, Now is the Son of man glorified, and God is glorified in him.
