'Fellow servant' in the Bible

And I fell at his feet to worship him; and he said to me: See that you do it not; I am your fellow-servant, and of your brethren that have the testimony of Jesus; worship God: for the testimony of Jesus is the spirit of prophecy.

And he said to me: See that you do it not; I am your fellow-servant, and of your brethren the prophets, and of those who keep the words of this book: worship God.
