And it came to pass, on the next day, when they had come down from the mountain and were come to the disciples, they saw a great multitude around them and scribes questioning with them. And immediately all the multitude, when they saw Him, were greatly astonished, and running to Him saluted Him. And He asked them, "What are ye discussing with them?'
And, behold, there came to Him a man from the multitude, kneeling down to Him, and saying, "Lord, have mercy! I beseech Thee, look upon my son: for he is my only child. He is lunatic, andsuffereth grievously, having a mute spirit. And wherever it seizeth him, he crieth out suddenly, and it convulseth him and dasheth him down; and he foameth, and grindeth his teeth, and pineth away; and having prostrated him, it with difficulty departeth from him; indeed, he often falleth into the fire and often into the water. And I brought him to Thy disciples and besought them to cast it out, and they were not able to heal him."
Then Jesus, answering, said, "O faithless and perverse generation, how long shall I be with you? How long shall I bear with you? Bring hither thy son to Me." And they brought him to Jesus. Now while he was yet coming, the demon, seeing Jesus, immediately threw him down and convulsed him grievously: and falling on the ground, he rolled, foaming. And Jesus asked his father, "How long a time is it since this began with him?"
And the father answered, "From childhood. And often it hath cast him into the fire and into the waters, to destroy him. But if Thou canst do anything, help us--have compassion on us!" Then Jesus said to him, "If thou canst!' All things are possible to him that believeth." Immediately the father of the child cried out and said, "I believe! Help Thou my unbelief." Then Jesus, seeing that the multitude came running together, rebuked the unclean spirit and healed the boy, saying to it, "Thou mute and deaf spirit, I command thee, come out of him, and enter into him no more."
And the demon, having cried out and convulsed him greatly, came out; and the boy was as if dead, so that the greater part said, "He is dead." But Jesus, taking him by his hand, raised him up, and he stood; and He gave him back to his father. And the boy was healed from that time. And they were all astonished at the majesty of God.
Then when Jesus had come into a house, His disciples came to Him and asked Him privately, "Why were we not able to cast it out?" And He saith to them, "Because of your little faith. For verily I say to you, If ye have faith as a grain of mustard seed, ye shall say to this mountain, 'Remove hence to yonder place,' and it will remove; and nothing shall be impossible to you. But this kind can be cast out in no way except through prayer and fasting."
