There is a very interesting interpretation of the case of the יפת תואר, the woman taken captive. Two different commentators have two dramatically opposed explanations of this case. On the one hand, the אורח חיים הקדוש says that the eventual marriage to this woman is a means towards freeing holy Jewish souls that were taken captive in the body of a non-Jew. This was part of a divine plan. The אלשיך הקדוש says the opposite. He says that because this relationship was based on lust and the attraction was far from holy, nothing good could come out of this union. If this woman were to marry the Jewish man, the offspring would be tainted and they would likely have a child who would be part of the ערב רב, the mixed multitude. It is very unusual to see two holy rabbis have such opposing explanations of a section of Torah.
