Colossians 4:8-10

For I have sent him to you for this very purpose, that you may know about our circumstances and that he may encourage your hearts; and with him Onesimus, our faithful and beloved brother, who is one of your number. They will inform you about the whole situation here. Aristarchus, my fellow prisoner, sends you his greetings; and also Barnabas’s cousin Mark (about whom you received instructions; if he comes to you, welcome him)
