'Brethren' in the Bible

We ought always to give thanks to God for you, brethren, as is only fitting, because your faith is greatly enlarged, and the love of each one of you toward one another grows ever greater;

Now we request you, brethren, with regard to the coming of our Lord Jesus Christ and our gathering together to Him,

But we should always give thanks to God for you, brethren beloved by the Lord, because God has chosen you from the beginning for salvation through sanctification by the Spirit and faith in the truth.

So then, brethren, stand firm and hold to the traditions which you were taught, whether by word of mouth or by letter from us.

Finally, brethren, pray for us that the word of the Lord will spread rapidly and be glorified, just as it did also with you;

Now we command you, brethren, in the name of our Lord Jesus Christ, that you keep away from every brother who leads an unruly life and not according to the tradition which you received from us.

But as for you, brethren, do not grow weary of doing good.
