I'm not one to memorize Bible passages, but I believe there are a few places where the Israelite were told to lay waste to other tribes, though they could keep the virgins for themselves.
This is the first I found via google, I'm sure you can find more:
“Have you allowed all the women to live?” he asked them. “They were the ones who followed Balaam’s advice and enticed the Israelites to be unfaithful to the Lord in the Peor incident, so that a plague struck the Lord’s people. Now kill all the boys. And kill every woman who has slept with a man, but save for yourselves every girl who has never slept with a man.
..and when exactly did God command Jewish people to rape? This comment is very strange
