Philemon 1:10-14

I beseech thee for my son Onesimus, whom I have begotten in my bonds: Which in time past was to thee unprofitable, but now profitable to thee and to me: Whom I have sent again: thou therefore receive him, that is, mine own bowels: Whom I would have retained with me, that in thy stead he might have ministered unto me in the bonds of the gospel: But without thy mind would I do nothing; that thy benefit should not be as it were of necessity, but willingly.
