When for instance anyone does something for the sake of his wife, children, grandchildren, sons-in-law, and daughters-in-law, he does it for his own sake since they are his own. The same is true of him who does it for the sake of other relatives, and for the sake of friends who go along with his love and thereby link themselves to him.
