Well, folks, it looks like God is really mad at the Israelites in Numbers 25. They were having a party, and apparently they were getting a little too friendly with some Moabite women. So God sends a plague, and the only way to make it stop is for a guy named Phinehas to take a spear and stab a couple of people. So, uh, lesson learned: don't go to parties with Moabite women.
