'Fellow servant' in the Bible

I prostrated myself at the feet of him who spoke to worship him, but he said to me- - 'Forbear; I am your fellow-servant, and the fellow-servant of your Brothers who bear their testimony to Jesus. Worship God. For to bear testimony to Jesus needs the inspiration of the Prophets.'

But he said to me-- 'Forbear; I am your fellow-servant, and the fellow-servant of your Brothers, the Prophets, and of all who lay to heart the words in this book. Worship God.'
