The Lord's Own Mouth

In Jewish Wannami 21, verse 10 onwards, if you notice among the captives a beautiful woman and are attracted to her, you may take her as your wife. I don't see a way of reading this that can be reconciled with an attitude that we're not really talking about slavery here. We're talking about something like people entering into a voluntary work contract. No, this is this is captives of war, who the captives find attractive, give them a month to mourn for the people who presumably were killed by their new husband - now they're yours to keep.
