John Chrysostom — as excerpted in the Catena Aurea on Mark 10:13-16

“(ubi sup.) But the disciples, out of regard for the dignity of Christ, forbade those who brought them. And this is what is added: And his disciples rebuked those who brought them. But our Saviour, in order to teach His disciples to be modest in their ideas, and to tread under foot worldly pride, takes the children to Him, and assigns to them the kingdom of God: wherefore it goes on: And he said unto them, Suffer little children to come unto me, and forbid them not.”
