'Brethren' in the Bible

We are bound to give thanks to God always to you, brethren, even as it is meet, for that your faith growth exceedingly, and the love of each one of you all toward one another aboundeth;

Now we beseech you, brethren, touching the coming of our Lord Jesus Christ, and our gathering together unto him;

But we are bound to give thanks to God always for you, brethren beloved of the Lord, for that God chose you from the beginning unto salvation in sanctification of the Spirit and belief of the truth:

So then, brethren, stand fast, and hold the traditions which ye were taught, whether by word, or by epistle of ours.

Finally, brethren, pray for us, that the word of the Lord may run and be glorified, even as also it is with you;

Now we command you, brethren, in the name of our Lord Jesus Christ, that ye withdraw yourselves from every brother that walketh disorderly, and not after the tradition which they received of us.

But ye, brethren, be not weary in well-doing.
