17And one of the multitude answered him, Teacher, I brought unto thee my son, who hath a dumb spirit; 18and wheresoever it taketh him, it dasheth him down: and he foameth, and grindeth his teeth, and pineth away: and I spake to thy disciples that they should cast it out; and they were not able. 19And he answereth them and saith, O faithless generation, how long shall I be with you? how long shall I bear with you? bring him unto me. 20And they brought him unto him: and when he saw him, straightway the spirit tare him grievously; and he fell on the ground, and wallowed foaming. 21And he asked his father, How long time is it since this hath come unto him? And he said, From a child. 22And oft-times it hath cast him both into the fire and into the waters, to destroy him: but if thou canst do anything, have compassion on us, and help us. 23And Jesus said unto him, If thou canst! All things are possible to him that believeth. 24Straightway the father of the child cried out, and said, I believe; help thou mine unbelief. 25And when Jesus saw that a multitude came running together, he rebuked the unclean spirit, saying unto him, Thou dumb and deaf spirit, I command thee, come out of him, and enter no more into him. 26And having cried out, and torn him much, he came out: and the boy became as one dead; insomuch that the more part said, He is dead. 27But Jesus took him by the hand, and raised him up; and he arose. 28And when he was come into the house, his disciples asked him privately, How is it that we could not cast it out? 29And he said unto them, This kind can come out by nothing, save by prayer.
