Colossians 4:8-10

I am sending him to you for this very purpose, that he may know your circumstances and comfort your hearts, with Onesimus, a faithful and beloved brother, who is one of you. They will make known to you all things which are happening here. Aristarchus my fellow prisoner greets you, with Mark the cousin of Barnabas (about whom you received instructions: if he comes to you, welcome him)
