'Brothers' in the Bible

If you keep these things before the minds of the brothers, you will be a good servant of Christ Jesus, trained in the words of the faith and of the right teaching which has been your guide:

Do not say sharp words to one who has authority in the church, but let your talk be as to a father, and to the younger men as to brothers:

And let those whose masters are of the faith have respect for them because they are brothers, working for them the more readily, because those who take part in the good work are of the faith and are dear. Give orders and teaching about these things.
