'Brother' in the Bible

He who says he is in the light, and hates his brother, is in the darkness until now.

He that loves his brother abides in light, and there is no occasion of stumbling in him.

But he that hates his brother is in the darkness, and walks in the darkness, and knows not where he goes, because the darkness has blinded his eyes.

In this are manifest the children of God and the children of the devil. Whoever does not practise righteousness is not of God, and he who does not love his brother.

not as Cain was of the wicked one, and slew his brother; and on account of what slew he him? because his works were wicked, and those of his brother righteous.

We know that we have passed from death to life, because we love the brethren. He who does not love his brother abides in death.

Every one that hates his brother is a murderer, and ye know that no murderer has eternal life abiding in him.

But whoso may have the world's substance, and see his brother having need, and shut up his bowels from him, how abides the love of God in him?

If any one say, I love God, and hate his brother, he is a liar: for he that loves not his brother whom he has seen, how can he love God whom he has not seen?

And this commandment have we from him, That he that loves God love also his brother.

If any one see his brother sinning a sin not unto death, he shall ask, and he shall give him life, for those that do not sin unto death. There is a sin to death: I do not say of that that he should make a request.
