Colossians 4:10, 11
My fellow prisoner Aristarchus sends you greetings, as does Mark the cousin of Barnabas. You have already received instructions about him: If he comes to you, welcome him. / Jesus, who is called Justus, also sends greetings. These are the only Jews among my fellow workers for the kingdom of God, and they have been a comfort to me.
2 Timothy 4:11
Only Luke is with me. Get Mark and bring him with you, because he is useful to me in the ministry.
Philemon 1:24
as do Mark, Aristarchus, Demas, and Luke, my fellow workers.
