Philemon 8-16

Therefore, though I have much boldness in Christ to command you to do what is proper,
9 yet for love’s sake I rather plead with you—since I am such a person as Paul, the aged, and now also a prisoner of Christ Jesus—
Plea for Onesimus
10 I plead with you for my child Onesimus, of whom I became a father in my chains,
11 who formerly was useless to you, but now is useful both to you and to me.
12 I have sent him back to you in person, that is, my very heart,
13 whom I intended to keep with me, so that on your behalf he might minister to me in my chains for the gospel,
14 but without your consent I did not want to do anything, so that your goodness would not be, in effect, by compulsion but voluntary.
15 For perhaps he was for this reason separated from you for a while, that you would have him back forever,
16 no longer as a slave, but more than a slave, a beloved brother, especially to me, but how much more to you, both in the flesh and in the Lord.
