Philemon 9-10 New Revised Standard Version (NRSV)
9 yet I would rather appeal to you on the basis of love—and I, Paul, do this as an old man, and now also as a prisoner of Christ Jesus.[a] 10 I am appealing to you for my child, Onesimus, whose father I have become during my imprisonment.
Philemon 12-17 New Revised Standard Version (NRSV)
12 I am sending him, that is, my own heart, back to you. 13 I wanted to keep him with me, so that he might be of service to me in your place during my imprisonment for the gospel; 14 but I preferred to do nothing without your consent, in order that your good deed might be voluntary and not something forced. 15 Perhaps this is the reason he was separated from you for a while, so that you might 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.
17 So if you consider me your partner, welcome him as you would welcome me.
