1 John 3:12

12 Do not be like Cain, who belonged to the evil one and murdered his brother. And why did he murder him? Because his own actions were evil and his brother’s were righteous.

1 John 3:15

15 Anyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him.
