The next day, when Jesus and the three disciples 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,” 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 impure spirit, healed the boy and gave him back to his father. And they were all amazed at the greatness of God.
While everyone was marveling at all that Jesus did, he said to his disciples, “Listen carefully to what I am about to tell you: The Son of Man is going to be delivered into the hands of men.” But they did not understand what this meant. It was hidden from them, so that they did not grasp it, and they were afraid to ask him about it.
An argument started among the disciples as to which of them would be the greatest. Jesus, knowing their thoughts, took a little child and had him stand beside him. Then he said to them, “Whoever welcomes this little child in my name welcomes me; and whoever welcomes me welcomes the one who sent me. For it is the one who is least among you all who is the greatest.”
“Master,” said John, “we saw someone driving out demons in your name and we tried to stop him, because he is not one of us.”
“Don’t stop him,” Jesus said, “for whoever is not against you is for you.”
