Mark 9:16-18

New Revised Standard Version Updated Edition

¹⁶ He asked them, “What are you arguing about with them?” ¹⁷ Someone from the crowd answered him, “Teacher, I brought you my son; he has a spirit that makes him unable to speak, ¹⁸ and whenever it seizes him, it dashes him down, and he foams and grinds his teeth and becomes rigid, and I asked your disciples to cast it out, but they could not do so.”
