17 Someone from the crowd answered him, “Teacher,ce I brought my son to you. He has a spiritcf that makes him unable to speak.cg 18 Whenever it seizes him, it throws him down, and he foams at the mouth, grinds his teeth, and becomes rigid. I asked your disciples to drive it out, but they couldn’t.”

19 He replied to them, “You unbelievingch generation, how long will I be with you? How long must I put up with you? Bring him to me.” 20 So they brought the boy to him. When the spirit saw him, it immediately threw the boy into convulsions. He fell to the ground and rolled around, foaming at the mouth.
