'Fellow worker' in the Bible

Greetings to Urbanus, our fellow-worker in [the service of] Christ, and my dear friend Stachys.

My fellow-worker Timothy sends his greetings to you, and so do my fellow-Jews Lucius, Jason and Sosipater. [See verse 7].

As for Titus, he is my partner and fellow-worker on your behalf. As for our brothers [i.e., those who will accompany him], they are the messengers of the churches and an honor to Christ.

For I do not have anyone else [i.e., as a fellow-worker] who thinks the same way I do, and who will genuinely care for your [spiritual and material] needs.

But I considered it necessary to send to you Epaphroditus, my brother, fellow-worker and fellow-soldier, and your messenger [to me] and minister to my needs.

and so we [i.e., I] sent Timothy, our brother and God's fellow-worker in [the ministry of] the Gospel, to strengthen and encourage you in your faith,

[This letter is from] Paul, a prisoner of Christ Jesus, and Timothy our brother, [and is being sent] to Philemon our dearly loved [brother] and fellow-worker,
