TSK · Philemon 1:24

So Barnabas and Saul returned to Jerusalem when they had completed their mission, bringing along with them John Mark.

Barnabas wanted to bring John called Mark along with them too,

We went on board a ship from Adramyttium that was about to sail to various ports along the coast of the province of Asia and put out to sea, accompanied by Aristarchus, a Macedonian from Thessalonica.

But for now I have considered it necessary to send Epaphroditus to you. For he is my brother, coworker and fellow soldier, and your messenger and minister to me in my need.

Aristarchus, my fellow prisoner, sends you greetings, as does Mark, the cousin of Barnabas(about whom you received instructions; if he comes to you, welcome him).

For Demas deserted me, since he loved the present age, and he went to Thessalonica. Crescens went to Galatia and Titus to Dalmatia.

Therefore we ought to support such people, so that we become coworkers in cooperation with the truth.
