The Cutting of Her Hair and Nails

The law of war and marriage is placed as a segue between the laws of war back in chapter 20 and the household laws that we've been discussing in 22. So we have a foreign woman who is ushered into the bit of of an Israelite family via marriage. The cutting of her hair and nails? Well many understand these as acts of mourning. And then you will be able to do that. You shall not take her out as she desires but you will certainly not sell her for money.
