Philemon 1:7-11
English Standard Version
8Accordingly, though I am bold enough in Christ to command you to do what is required,
9yet for love 's sake I prefer to appeal to you — I, Paul, an old man and now a prisoner also for Christ Jesus —
10I appeal to you for my child, Onesimus, whose father I became in my imprisonment.
11(Formerly he was useless to you, but now he is indeed useful to you and to me.)
