BLB(i)
7 Beloved, I am not writing a new commandment to you, but an old commandment, which you have had from the beginning. The old commandment is the word that you have heard.
8 Again, I am writing a new commandment to you, which is true in Him and in you, because the darkness is passing away and the true light already shines.
9 The one claiming to be in the light and hating his brother is in the darkness even until now.
10 The one loving his brother abides in the light, and in him there is no cause for stumbling.
