'Brother' in the Bible

He who says that he is in the light, and has hate in his heart for his brother, is still in the dark.

He who has love for his brother is in the light, and there is no cause of error in him.

But he who has hate for his brother is in the dark, walking in the dark with no knowledge of where he is going, unable to see because of the dark.

In this way it is clear who are the children of God and who are the children of the Evil One; anyone who does not do righteousness or who has no love for his brother, is not a child of God.

Not being of the Evil One like Cain, who put his brother to death. And why did he put him to death? Because his works were evil and his brother's works were good.

Anyone who has hate for his brother is a taker of life, and you may be certain that no taker of life has eternal life in him.

But if a man has this world's goods, and sees that his brother is in need, and keeps his heart shut against his brother, how is it possible for the love of God to be in him?

If a man says, I have love for God, and has hate for his brother, his words are false: for how is the man who has no love for his brother whom he has seen, able to have love for God whom he has not seen?

And this is the word which we have from him, that he who has love for God is to have the same love for his brother.

If a man sees his brother doing a sin which is not bad enough for death, let him make a prayer to God, and God will give life to him whose sin was not bad enough for death. There is a sin whose punishment is death: I do not say that he may make such a request then.
