'Brothers' in the Bible

If you point these things out to the brothers, you will be a good servant of Christ Jesus, nourished by the words of the faith and the good teaching that you have followed.

Do not rebuke an older man, but exhort him as a father, younger men as brothers,

Those who have believing masters should not be disrespectful to them because they are brothers, but should serve them better, since those who benefit from their service are believers and dearly loved.Teach and encourage these things.
