'Fellow workers' in the Bible

Yes, and I am asking you also, [my] faithful partner [Note: This person is unknown, but may have been one of Paul's preacher companions], help those women, for they have worked hard with me in [spreading] the Gospel, along with Clement also, and the rest of my fellow-workers, whose names are in the book of life. [See Rev. 3:5; Heb. 12:23].
