Musar su Salmi 145:21

In פרשת מטות the Torah deals with laws designed to perfect our souls, our spiritual development. The laws dealing with vows contain the warning to honor all our utterances, ככל היוצא מפיו יעשה "he must carry out all that crosses his lips" (Numbers 30,4). This is addressed to the soul, because the power of speech derives from the attribute of wisdom which itself is an outgrowth of the soul. Speech is only an externalized version of one's thoughts, something that elevates man above all other living creatures. Man is called a מדבר, "a talking creature." This is why he must not "profane" his word, "לא יחל דברו." We also find that Onkelos renders Genesis 2,7: ויהי האדם לנפש חיה as "man became a talking spirit." You are already aware that man has been designed along the superior lines of a higher world, that each one of his limbs is a branch of a "tree" in the Celestial Regions, and that the mouth he has been equipped with is meant only to enable him to proclaim the greatness of the Lord and to tell His praises. It is a vessel to be used only for the service of the Lord. This is what David meant when he said in Psalms 145,21: "My mouth shall utter the praise of the Lord."

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."
