Expert Sources on Disturbing Old Testament Bible Verses

What are the most disturbing bible verses you know? I'm putting together research for an article. I've noticed most christians don't seem to have any idea what they're following or subscribing to. Because they don't read the old testament. I always say I don't have beef with Jesus, his teachings seem good at the surface, but I see GOD as something entirely different that I'd NEVER worship and find extremely evil. Awareness of these verses need to be spread. So! Hit me with the verse, and context surrounding it. Feel free to add more than one.
