'Brethren' in the Bible

For both he that sanctifieth and they that are sanctified are all of one: for which cause he is not ashamed to call them brethren,

saying, I will declare thy name unto my brethren, In the midst of the congregation will I sing thy praise.

Wherefore it behooved him in all things to be made like unto his brethren, that he might become a merciful and faithful high priest in things pertaining to God, to make propitiation for the sins of the people.

Wherefore, holy brethren, partakers of a heavenly calling, consider the Apostle and High Priest of our confession, even Jesus;

Take heed, brethren, lest haply there shall be in any one of you an evil heart of unbelief, in falling away from the living God:

And they indeed of the sons of Levi that receive the priest's office have commandment to take tithes of the people according to the law, that is, of their brethren, though these have come out of the loins of Abraham:

Having therefore, brethren, boldness to enter into the holy place by the blood of Jesus,

Let love of the brethren continue.

But I exhort you, brethren, bear with the word of exhortation, for I have written unto you in few words.
