'Brother' in the Bible

But it seemed to me necessary to send to you Epaphroditus, my brother, who has taken part with me in the work and in the fight, and your servant, sent by you for help in my need;

And I make request to you, true helper in my work, to see to the needs of those women who took part with me in the good news, with Clement and the rest of my brother-workers whose names are in the book of life.
