'Brother' in the Bible

But let the brother of low position be glad that he is lifted up;

If a brother or a sister is without clothing and in need of the day's food,

Do not say evil against one another, my brothers. He who says evil against his brother or makes himself his brother's judge, says evil against the law and is judging the law: and in judging the law you become, not a doer of the law but a judge.
