Mark 9:16-18

New Catholic Bible

¹⁶ He asked them, “What are you arguing about with them?”

¹⁷ A man in the crowd answered him, “Teacher, I have brought you my son who is possessed by a spirit that makes him unable to speak. ¹⁸ Wherever it seizes him, it flings him to the ground, and he foams at the mouth, grinds his teeth, and becomes rigid. I asked your disciples to drive it out, but they were unable to do so.”
