'Fellow servant' in the Bible

Then his fellow-servant fell at his feet, and besought him, saying, Have forbearance with me, and I will pay thee all.

and oughtest thou not to have had compassion on thy fellow-servant, even as I had pity on thee?

All my affairs will Tychicus make known unto you, a beloved brother, and faithful minister, and fellow-servant in the Lord:

And I fell down before his feet to worship him: and he said unto me, See thou dost not so: I am thy fellow-servant, and of thy brethren who hold the testimony of Jesus: worship God: for the spirit of prophecy is the testimony of Jesus.

And he said to me, See thou do it not; for I am a fellow-servant of thine, and of thy brethren the prophets, and of those who observe the words of this book: worship God.
