Luke 9:37-42 New American Bible, Revised Edition (NABRE)

37. On the next day, when they came down from the mountain, a large crowd met him.

38. There was a man in the crowd who cried out, “Teacher, I beg you, look at my son; he is my only child.

39. For a spirit seizes him and he suddenly screams and it convulses him until he foams at the mouth; it releases him only with difficulty, wearing him out.

40. I begged your disciples to cast it out but they could not.”

41. Jesus said in reply, “O faithless and perverse generation, how long will I be with you and endure you? Bring your son here.”

42. As he was coming forward, the demon threw him to the ground in a convulsion; but Jesus rebuked the unclean spirit, healed the boy, and returned him to his father.
