'Brother' in the Bible

But thou, why dost thou judge thy brother? or thou again, why dost thou set at nought thy brother? for we shall all stand before the judgment-seat of God.

Let us not therefore judge one another any more: but judge ye this rather, that no man put a stumblingblock in his brother's way, or an occasion of falling.

For if because of meat thy brother is grieved, thou walkest no longer in love. Destroy not with thy meat him for whom Christ died.

It is good not to eat flesh, nor to drink wine, nor to do anything whereby thy brother stumbleth.

Gaius my host, and of the whole church, saluteth you. Erastus the treasurer of the city saluteth you, and Quartus the brother.
