37 Next day, when they came down the hill, a large crowd met him.
38 "Teacher," shouted a man from the crowd, "look at my son, I beg of you, for he is my only boy,
39 and a spirit gets hold of him till he suddenly shrieks; it convulses him till he foams; indeed it will hardly leave off tearing him to pieces.
40 I begged your disciples to cast it out, but they could not."
41 Jesus answered, "O faithless and perverse generation, how long must I still be with you and bear with you? Fetch your son here."
42 Before the boy could reach Jesus, the daemon dashed him down and convulsed him, but Jesus checked the unclean spirit, cured the boy, and handed him back to his father.
