17 A man from the crowd answered Him, "Teacher, I brought my son to you, for he has a dumb spirit.
18 Wherever it seizes him, it convulses him, and he foams at the mouth and grinds his teeth; and he is wasting away. So I asked your disciples to drive it out, but they could not do it."
19 He answered them, "Oh, you unbelieving people of the times! How long must I be with you! How long must I put up with you! Bring him to me."
20 And they brought the boy to Him. As soon as the spirit saw Him, it convulsed the boy, and he fell on the ground and kept rolling over and foaming at the mouth.
21 Then He asked his father, "How long has he been like this?" He answered, "From his childhood;
22 and many a time it has thrown him into the fire or into the water, to destroy him. But if there is anything you can do for him, do pity us and help us!"
23 Jesus said to him, "If there is anything I can do! Everything is possible for him who has faith!"
24 The boy's father at once cried out and said, "I do have faith; help my lack of faith!"
25 Then Jesus, because He saw that a crowd was rushing up to Him, reproved the foul spirit and said to it, "You deaf and dumb spirit, get out of him, I charge you, and never get into him again."
