1 John 2: 9 - 11
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.
1 John 3:15
Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life
abiding in him.
1 John 4:20
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?
