'Fellow servant' in the Bible

as ye learned of Epaphras our dear fellow servant, which is for you a faithful minister of Christ,

The dear brother Tychicus shall tell you of all my business, which is a faithful minister, and fellow servant in the Lord,

And I fell at his feet, to worship him. And he said unto me, "See thou do it not. For I am thy fellow servant, and one of thy brethren, and of them that have the testimony of Jesus. Worship God. For the testimony of Jesus is the spirit of prophecy."

And he said unto me, "See thou do it not, for I am thy fellow servant and the fellow servant of thy brethren the prophets and of them which keep the sayings of this book. But worship God."
