Philemon 1:12 KJV

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 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.
