'Fellow servant' in the Bible

And I fell at his feet to worship him: and he said unto me, See thou do it not: I am thy fellow-servant, and a fellow-servant of thy brethren, that hold the testimony of Jesus. Worship God. For the Spirit of prophecy is the testimony of Jesus.

And he said unto 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.
