Philemon 1:10-14

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.
