Brethren, I write no new commandment unto you, but an old commandment which ye have had from the beginning. The old commandment is the Word which ye have heard from the beginning.
Again, a new commandment I write unto you, which thing is true in Him and in you, because the darkness is past and the true light now shineth.
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 no occasion for 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.
