Alright, so Deuteronomy 21. This one's about a bunch of rules for the Israelites, like what to do if you capture a female prisoner of war or find a dead body in the middle of nowhere. So, if you find yourself in a situation like that, you know what to do. Just be sure to wash your hands afterward. Also, the chapter talks about appointing a king, which I guess is cool if you're into that kind of thing. Anyway, it's all pretty dry, so just stick to the rules and you'll be alright.
