'Brethren' in the Bible

for I rejoiced exceedingly, brethren coming and testifying of the truth in thee, even as thou in truth dost walk;

Beloved, faithfully dost thou do whatever thou mayest work to the brethren and to the strangers,

because of this, if I may come, I will cause him to remember his works that he doth, with evil words prating against us; and not content with these, neither doth he himself receive the brethren, and those intending he doth forbid, and out of the assembly he doth cast.
