Philemon 1:10-13

10I appeal to you for my child Onesimus,1 whose father I became while I was in chains. 11Formerly he was useless to you, but now he has become useful both to you and to me. 12I am sending back to you him who is my very heart.

13I would have liked to keep him with me, so that on your behalf he could minister to me in my chains for the gospel.
