[37] The next day, when they came down from the mountain, a large crowd met him. [38] A man in the crowd called out, “Teacher, I beg you to look at my son, for he is my only child. [39] 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. [40] I begged your disciples to drive it out, but they could not.” [41] “You unbelieving and perverse generation,” Jesus replied, “how long shall I stay with you and put up with you? Bring your son here.” [42] 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. [43] And they were all amazed at the greatness of God. While everyone was marveling at all that Jesus did, he said to his disciples, [44] “Listen carefully to what I am about to tell you: The Son of Man is going to be delivered into the hands of men.” [45] 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. [46] An argument started among the disciples as to which of them would be the greatest. [47] Jesus, knowing their thoughts, took a little child and had him stand beside him. [48] 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.” [49] “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.” [50] “Do not stop him,” Jesus said, “for whoever is not against you is for you.”
