Philemon 1:12 WEB

¹⁰  I beg you for my child, whom I have become the father of in my chains, Onesimus,{Onesimus means 'useful.'}

¹¹  who once was useless to you, but now is useful to you and to me.

¹²  I am sending him back. Therefore receive him, that is, my own heart,

¹³  whom I desired to keep with me, that on your behalf he might serve me in my chains for the Gospel.

¹⁴  But I was willing to do nothing without your consent, that your goodness would not be as of necessity, but of free will.
