Philemon 1:8-16 NKJV
Therefore, though I might be very bold in Christ to command you what is fitting, yet for love’s sake I rather appeal to you—being such a one as Paul, the aged, and now also a prisoner of Jesus Christ— I appeal to you for my son Onesimus, whom I have begotten while in my chains, who once was unprofitable to you, but now is profitable to you and to me.
I am sending him back. You therefore receive him, that is, my own heart, whom I wished to keep with me, that on your behalf he might minister to me in my chains for the gospel. But without your consent I wanted to do nothing, that your good deed might not be by compulsion, as it were, but voluntary.
For perhaps he departed for a while for this purpose, that you might receive him forever, 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.
