19 He answered them, "O faithless generation, how long must I still be with you? how long have I to bear with you? Bring him to me."
20 So they brought the boy to him, and when the spirit saw Jesus it at once convulsed the boy; he fell on the ground and rolled about, foaming at the mouth.
21 Jesus asked his father, "How long has he been like this?" "From childhood," he said;
22 "it has thrown him into fire and water many a time, to destroy him. If you can do anything, do help us, do have pity on us."
23 Jesus said to him, "'If you can'! Anything can be done for one who believes."
24 At once the father of the boy cried out, "I do believe; help my unbelief."
25 Now as Jesus saw that a crowd was rapidly gathering, he checked the unclean spirit. "Deaf and dumb spirit," he said, "leave him, I command you, and never enter him again."
26 And it did come out, after shrieking aloud and convulsing him violently. The child turned like a corpse, so that most people said, "he is dead";
27 but, taking his hand, Jesus raised him and he got up.
28 When he went indoors his disciples asked him in private, "Why could we not cast it out?"
29 He said to them, "Nothing can make this kind come out but prayer and fasting."
