'Fellow servant' in the Bible

Then his fellow-servant having fallen at his feet besought him, saying, Be slow to anger towards me, and I will give back all to thee.

Oughtest thou not also to pity thy fellow-servant, as I also pitied thee

As also ye learned from Epaphras our beloved fellowservant, who is a faithful servant of Christ for you;

All things concerning me shall Tychicus make known to you, a dearly beloved brother, and a faithful servant and fellowservant in the Lord:

And I fell before his feet to worship him. And he says to me, See, not: I am thy fellowservant, and of thy brethren having the testimony of Jesus: worship God: for the testimony of Jesus is the spirit of prophecy.

And he says to me, See, not: for I am thy fellowservant, and of thy brethren the prophets, and of them keeping the words of the prophecy of this book; worship God.
