Musar su Deuteronomio 21:10

The Sifri has stated that Deut. 21,10 speaks about a permissible expansionary war, and that the legislation introduced by the words: וראית בשביה אשת יפת תואר applies only when such a war is fought outside the boundaries of Israel, whereas when a war is fought on the soil of Israel the command: לא תחיה כל נשמה, "you must not take any prisoners," applies. The reason is that within the boundaries of the land of Israel both harlots, i.e. Lilith as well as Machalat, can easily be eliminated. This is the mystical dimension of Joshua sending two spies in order to totally defeat these two harlots, as did indeed happen during the rule of King Solomon.

It is well known that in order to rehabilitate oneself spiritually one must exercise תשובה, תפלה וצדקה, repentance, prayer and the performance of charitable deeds. All of these three factors of man's rehabilitation depend on his mouth. Prayer and the reciting of G–d's praises are, of course, functions of the mouth. We know that repentance has to include verbalizing one's confession and one's resolution not to sin again. The Torah in 30,14 mentions that Torah is easy of access, i.e. בפיך ובלבבך לעשות. Rabbi Yitzchak says (Eruvin 54) that the Torah is easy to fulfill, לעשות, once one has repented both by mouth and in one's heart. Confession of one's sins with a broken heart is the principal ingredient of repentance. Charity, too, involves the mouth. Our sages (Baba Batra 9b) say that anyone who gives charity acquires six blessings; if someone also tries to make the recipient feel better by kind and encouraging words he will qualify for eleven blessings. Interestingly enough we have three words which symbolize three aspects of repentance, i.e. צום, קול, ממון, each one of which has a numerical value of 136. This suggests that all three aspects of תשובה are of equal importance. Stated differently, תשובה, צדקה, and תפלה equal קול. The very first part of our פרשה alludes to all the three ingredients of repentance. The Torah speaks about going to war, the plain meaning of which refers, of course, to actual warfare and battles with the enemy. Over and beyond this, however, the paragraph refers to the ongoing battle between man and his evil urge. Many of our commentators are at pains to point this out in their commentary on the relevant section in פרשת שופטים when they comment on the verse discussing the siege laid to a city (20,19). In actual fact, the war with his evil urge is the greatest battle man has to fight in this life. The matter is illustrated in the Talmud by the story of the elderly sage who met soldiers of the army of Alexander the Great at the time of his victorious return from a major battle. These soldiers were in a very exuberant frame of mind. The sage, while he congratulated them on their victory, pointed out that the victory they had won was minor, and that they had to get ready for the battle of their lives against the evil urge. This is what the sages meant when they described the whole paragraph of the יפת תואר as an illustration of man's ongoing battle against his baser instincts (Kidushin 21). By extending this allegory a little further we may come to understand the whole reason why a מלחמת רשות, a war which is expansionary, is allowed: We are always permitted to conduct aggressive action against our evil urges. We can be sure of G–d's ongoing support in that undertaking once we make the first move in the struggle against the evil urge. Our sages point out that we would be unable to subdue the יצר הרע without G–d's active assistance, but that we have G–d's promise: ונתנו בידו, "He will deliver him (the evil urge) into your hand" (21,10). It is significant that the Torah here employs the singular whereas in פרשת שופטים it speaks in the plural (20,2—20,3--20,4). This may be a reminder that the fight against the evil urge can only be fought on a person-to-person basis. We have a tradition that a nation neither succumbs to another nation nor to the Jewish people unless its protective spirit in the Celestial Regions had first suffered defeat. We have pointed out examples of this such as Israel observing "Egypt" instead of "Egyptians" "dead on the beaches of the sea" (Exodus 14,30). We learn from all this that our enemy (the evil urge), assumes many guises, i.e. attacks us in the plural, and this is why the Torah always describes our enemy in the plural (אויביכם, אל תערצו מפניהם). We have to battle all these manifold "enemies" because each transgression we commit creates a negative force in the world which comes back to haunt us. All of these negative forces created by our very selves are presided over and directed against us by Samael/Satan/Angel of Death, etc. The Torah describes victory over this multifaceted but essentially single force with the words: ונתנו ה' אלוקיך בידך ושבית שביו, "The Lord your G–d will deliver him into your hand and you will take him captive." Taking this enemy prisoner is possible only with the help of Torah study and מצוה observance. David describes this victory over the evil works in Psalms 68,19: He speaks about: עלית למרום שבית שבי, "You went up to the heights, having taken captives."

We similarly find that when Jacob was embattled against the Emorites that he referred to his conquest of the city of Shechem as something he had acquired by means of "my sword and my bow" (Genesis 48,22). There was another element to this battle: The prayer Jacob offered up helped him succeed. Onkelos translates the words בחרבי ובקשתי as בצלותי ובבעותי, "with my prayer and my entreaty." It was Jacob's custom that whenever he was involved in a confrontation he would employ three kinds of weapons which our Rabbis have referred to as מלחמה, דורון, תפלה. These may be considered as Jacob's "secret weapons." The weapon called דורון, was gifts to charity; the weapon called מלחמה was the struggle against his evil urge; the weapon called תפלה needs no homiletical interpretation. These three weapons together are what are popularly known as הקול קול יעקב. The weapon of charity is also alluded to in a Biblical passage describing soldiers going into battle. Psalms 85,14 speaks of: צדק לפניו יהלוך וישם לדרך פעמיו, "Charity goes before him as he sets out on his way." We also have a verse in Exodus 30,12 ונתנו איש כופר נפשו, suggesting that a man can use his charitable gifts to help him overcome his blood-guilt, i.e. to save him from danger in war. The fact that only men over the age of twenty had to make this contribution is a clear indication that once one is of military age it may become a life-saver.
