“Whom I would have retained with me, that in thy stead he might have ministered unto me in the bonds of the gospel:”
King James Version (KJV)
1:13 To serve me in thy stead - To do those services for me which thou, if present, wouldest gladly have done thyself.
Phm 1:13 Whom I would have retained with me. Would gladly have kept him with me to render for thee the service you would be glad to give me while I am in chains.
