Deuteronomy 21:12,13 Why did the women have to do the things in these verses?

Question: Why does the womwn has to do that in deuteronomy 21:12 & 13. Answer: There was a great potential for abuse when taking a captive woman as a wife, so God gave specific guidelines to govern this practice.  First the woman had to be purified and humbled (v12).  Then the woman would have to show that she no longer had any ties to her old nation and had become a citizen of Israel (v13).  -PG
