'Brethren' in the Bible

We ought to thank God always for you, brethren, even as it is meet, because your faith increases exceedingly, and the love of each one of you all towards one another abounds;

Now we beg you, brethren, by the coming of our Lord Jesus Christ and our gathering together to him,

But we ought to give thanks to God always for you, brethren beloved of the Lord, that God has chosen you from the beginning to salvation in sanctification of the Spirit and belief of the truth:

So then, brethren, stand firm, and hold fast the instructions which ye have been taught, whether by word or by our letter.

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

Now we enjoin you, brethren, in the name of our Lord Jesus Christ, that ye withdraw from every brother walking disorderly and not according to the instruction which he received from us.

But ye, brethren, do not faint in well-doing.
