'Fellow worker' in the Bible

Greet Urbanus, our fellow worker in Christ, and Stachys my beloved.

Timothy, my fellow worker, greets you, as do Lucius, and Jason, and Sosipater, my kinsmen.

As for Titus, he is my partner and fellow worker among you; and as for our brethren, they are messengers of the churches, a glory to Christ.

But I thought it necessary to send to you Epaphroditus, my brother and fellow worker and fellow soldier, who is also your messenger and minister to my need;

and we sent Timothy, our brother and God's fellow worker in the gospel of Christ, to strengthen and encourage you in your faith,

Paul, a prisoner of Christ Jesus, and Timothy our brother, to Philemon our beloved brother and fellow worker,
