'Fellow servant' in the Bible

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

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