Philemon 1:9-11

9 yet for love's sake I prefer to appeal to you—since I am such a person as Paul, an old man, and now also a prisoner [for the sake] of Christ Jesus—

10 I appeal to you for my [own spiritual] child Onesimus, whom I have fathered [in the faith] while a captive in these chains.

11 Once he was useless to you, but now he is indeed[5] useful to you as well as to me.
