'Fellow workman' in the Bible

salute Arbanus, our fellow-workman in Christ, and Stachys, my beloved;

Salute you do Timotheus, my fellow-workman, and Lucius, and Jason, and Sosipater, my kindred;

And I thought it necessary Epaphroditus -- my brother, and fellow-workman, and fellow-soldier, and your apostle and servant to my need -- to send unto you,

and did send Timotheus -- our brother, and a ministrant of God, and our fellow-workman in the good news of the Christ -- to establish you, and to comfort you concerning your faith,
