Luke 9:39-41

Revised Standard Version Catholic Edition

³⁹ and behold, a spirit seizes him, and he suddenly cries out; it convulses him till he foams, and shatters him, and will hardly leave him. ⁴⁰ And I begged your disciples to cast it out, but they could not.” ⁴¹ Jesus answered, “O faithless and perverse generation, how long am I to be with you and bear with you? Bring your son here.”
