1 John 2.9-11

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

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

11 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 3.10-15

10 “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.

11 For this is the message that ye heard from the beginning, that we should love one another.

12 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.

13 Marvel not, my brethren, if the world hate you.

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

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