'Brother' in the Bible

Paul, a prisoner of Jesus Christ, and Timothy our brother, unto Philemon our dearly beloved, and fellowlabourer,

And to Apphia, our sister, and to Archippus, our brother in God's army, and to the church in your house:

I give continual thanks to my God while making mention of you, my brother, in my prayers,

For we have great joy and consolation in thy love, because the bowels of the saints are refreshed by thee, brother.

Not now as a servant, but above a servant, a brother beloved, specially to me, but how much more unto thee, both in the flesh, and in the Lord?

If then you take me to be your friend and brother, take him in as myself.

Yea, brother, let me have joy of thee in the Lord: refresh my bowels in the Lord.

Epaphras, my brother-prisoner in Christ Jesus, sends you his love;

And so do Mark, Aristarchus, Demas, and Luke, my brother-workers.
