Colossians 4:10-11

10Aristarchus, my fellow prisoner, wishes to be remembered to you; as does Mark, the cousin of Barnabas (about whom you received instructions; if he comes to you, welcome him);

11and from Jesus, who is called Justus. These are the only fellow workers for the kingdom of God who are from the circumcision (Jewish Christians), and they have proved to be an encouragement and a comfort to me.
