'Brother' in the Bible

Paul, an Apostle of Jesus Christ by the purpose of God, and Sosthenes the brother,

My brothers, it is because of you that I have taken Apollos and myself as examples of these things, so that in us you might see that it is not wise to go farther than what is in the holy Writings, so that no one of you may be lifted up against his brother.

For who made you better than your brother? or what have you that has not been given to you? but if it has been given to you, what cause have you for pride, as if it had not been given to you?

But the sense of my letter was that if a brother had the name of being one who went after the desires of the flesh, or had the desire for other people's property, or was in the way of using violent language, or being the worse for drink, or took by force what was not his, you might not keep company with such a one, or take food with him.

But a brother who has a cause at law against another takes it before Gentile judges.

But to the rest I say, and not the Lord; If a brother has a wife who is not a Christian, and it is her desire to go on living with him, let him not go away from her.

For the husband who has not faith is made holy through his Christian wife, and the wife who is not a Christian is made holy through the brother: if not, your children would be unholy, but now are they holy.

But if the one who is not a Christian has a desire to go away, let it be so: the brother or the sister in such a position is not forced to do one thing or the other: but it is God's pleasure that we may be at peace with one another.

And so, through your knowledge, you are the cause of destruction to your brother, for whom Christ underwent death.

For this reason, if food is a cause of trouble to my brother, I will give up taking meat for ever, so that I may not be a cause of trouble to my brother.

But as for Apollos, the brother, I had a great desire for him to come to you with the brothers, but it was not his pleasure to come now; but he will come when he has a chance.
