Philemon 1:10-14

I appeal to you for my child Onesimus, whom I have begotten in my imprisonment, who formerly was useless to you, but now is useful both to you and to me. I have sent him back to you in person, that is, sending my very heart, whom I wished to keep with me, so that on your behalf he might minister to me in my imprisonment for the gospel; but without your consent I did not want to do anything, so that your goodness would not be, in effect, by compulsion but of your own free will.
