 He goes on to say later on, anger, the same thing. Okay, I haven't murdered this person I don't like, but have I hated them? Jesus isn't just upping the ante. He's trying to get us to understand the motivation. Okay, maybe I haven't murdered anybody, but I've hated some people. And in God's eyes, I'm guilty of murder. I'm the same lawbreaker as the person who actually does the deed.
