'Brother' in the Bible

Let the brother in humble circumstances glory in his high position [as a born-again believer, called to the true riches and to be an heir of God];

If a brother or sister is without [adequate] clothing and lacks [enough] food for each day,

Believers, do not speak against or slander one another. He who speaks [self-righteously] against a brother or judges his brother [hypocritically], speaks against the Law and judges the Law. If you judge the Law, you are not a doer of the Law but a judge of it.
