'Brother' in the Bible

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

He that loveth his brother abideth in the light, and there is none occasion of stumbling in him.

But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that 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, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous.

We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death.

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

We know what love is--through Christ's having laid down His life on our behalf; and in the same way we ought to lay down our lives for our brother men.

But whoso hath this world's good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God 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, how can he 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 sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it.
