'Fellow servant' in the Bible

And I fell at his feet to worship him; and he saith to me, See thou do it not; I am a fellowservant of thee, and of thy brethren who maintain the testimony to Jesus; worship God. For the testimony to Jesus is the spirit of prophecy.

And he saith to me, See thou do it not; I am a fellowservant of thee, and of thy brethren the prophets, and of those who keep the words of this book; worship God.
