John Chrysostom
To ask in this way that they pray belongs only to one who loves them deeply. He says, do not simply pray, but pray with all diligence that I may come to you sooner. To desire so much to come to them, and to ask them to pray for him, belongs to one who is conscious of nothing against himself. Therefore, having first asked prayers from them for himself, he then prays to God for every good thing for them.
