Luke 9:39-41

New Revised Standard Version, Anglicised

³⁹ Suddenly a spirit seizes him, and all at once he^[a] shrieks. It throws him into convulsions until he foams at the mouth; it mauls him and will scarcely leave him. ⁴⁰ I begged your disciples to cast it out, but they could not.’ ⁴¹ Jesus answered, ‘You faithless and perverse generation, how much longer must I be with you and bear with you? Bring your son here.’
