The next day, when they came down from the mountain, a large crowd met him.
A man in the crowd called out, "Teacher, I beg you to look at my son, for he is my only child.
A spirit seizes him and he suddenly screams; it throws him into convulsions so that he foams at the mouth. It scarcely ever leaves him and is destroying him.
I begged your disciples to drive it out, but they could not."
"You unbelieving and perverse generation,"1 Jesus replied, "how long shall I stay with you and put up with you? Bring your son here."
Even while the boy was coming, the demon threw him to the ground in a convulsion. But Jesus rebuked the evil spirit, healed the boy and gave him back to his father.
