'Brother' in the Bible

Paul, an apostle of Christ Jesus through the will of God, and Timothy our brother, to the church of God that is in Corinth, together with all the saints who are in all Achaia.

I did not experience rest in my spirit, [because] I did not find Titus my brother, but saying farewell to them, I departed for Macedonia.

And we have sent at the same time with him the brother whose praise in the gospel [has become known] throughout all the churches.

And we are sending with them our brother whom we have tested many times in many [things] that he is diligent, but now much more diligent [because of his] great confidence in you.

I urged Titus [to go], and I sent the brother [with him]. Titus did not take advantage of you, [did he]? Did we not conduct ourselves in the same spirit? Did we not walk in the same footsteps?
