I send greetings to Priscilla and Aquila, my fellow-workers in [the service of] Christ Jesus.

For we are all fellow-workers in God's service; you people are God's farm land; [you are] God's building.

Yes, and I am asking you also, [my] faithful partner [Note: This person is unknown, but may have been one of Paul's preacher companions], help those women, for they have worked hard with me in [spreading] the Gospel, along with Clement also, and the rest of my fellow-workers, whose names are in the book of life. [See Rev. 3:5; Heb. 12:23].

Jesus, who is called Justus, also sends his greetings. These men are the only Jews among my fellow-workers for God's kingdom; they have proved to be an encouragement to me.

So, when we could not stand it any longer [Note: Paul's concern for the spiritual well-being of the Thessalonian Christians became unbearable], we [i.e., I, See verse 5] thought it best to be left behind, alone, at Athens [Note: Paul was willing to labor alone at Athens, so he could send his fellow-workers to minister to others. See Acts 17],

Luke is the only one [of my fellow-workers still] with me. Pick up Mark and bring him with you for he [will be] helpful to me in [my] ministry.

along with [John] Mark [Note: This shows that Mark was now back in the good graces of Paul. See Acts 15:36-40], Aristarchus, Demas [Note: This man later deserted Paul. See II Tim. 4:10] and Luke, who are [also] my fellow-workers. [Note: These men, unlike Epaphras who was imprisoned with Paul, were free to minister for Christ there in Rome].

Therefore, we should show hospitality to such men, so that we can be fellow-workers [with them] in [the cause of] the truth.
