'Fellow servant' in the Bible

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

Then saith he to me, See thou do it not: for I am thy fellow-servant, and of thy brethren the prophets, and of them who keep the sayings of this book: worship God.
