'Hate' 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.

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.

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.

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?
