'Brethren' in the Bible

For I rejoiced greatly, when the brethren came and testified of the truth that is in thee, even as thou walkest in the truth.

Beloved, thou doest faithfully whatsoever thou doest to the brethren, and to strangers;

Wherefore, if I come, I will remember his deeds which he doeth, prating against us with malicious words: and not content therewith, neither doth he himself receive the brethren, and forbiddeth them that would, and casteth them out of the church.
