1 John 2:7-11 HNV

7 Brothers, I write no new mitzvah to you, but an old mitzvah which you had from the beginning. The old mitzvah is the word which you heard from the beginning.
8 Again, I write a new mitzvah to you, which thing is true in him and in you; because the darkness is passing away, and the true light already shines.
9 He who says he is in the light and hates his brother, is in the darkness even until now.
10 He who loves his brother remains in the light, and there is no occasion for stumbling in him.
11 But he who hates his brother is in the darkness, and walks in the darkness, and doesn't know where he is going, because the darkness has blinded his eyes.
