'Brother' in the Bible

He that saith he is in the light and hateth his brother, is in the darkness even until now.

He that loveth his brother abideth in the light, and there is no occasion of stumbling in him.

But he that hateth his brother is in the darkness, and walketh in the darkness, and knoweth not whither he goeth, because the darkness hath blinded his eyes.

In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.

not as Cain was of the evil one, and slew his brother. And wherefore slew he him? Because his works were evil, and his brother's righteous.

Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.

But whoso hath the world's goods, and beholdeth his brother in need, and shutteth up his compassion from him, how doth the love of God abide in him?

If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, cannot love God whom he hath not seen.

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

If any man see his brother sinning a sin not unto death, he shall ask, and God will give him life for them that sin not unto death. There is a sin unto death: not concerning this do I say that he should make request.
