Musar su I Samuele 15:29

I have written about the mystical dimension of the prohibition to carry objects on the Sabbath from the private domain into the public domain in my treatise on שבת. I have found an interesting article by the Ari zal on the subject of תחומים, the restriction of man's movements beyond a certain distance outside his home or city on the Sabbath. These are his words: "I have now decided to tell you that the biblical injunction is not to walk on the Sabbath beyond י"ב מיל (14,4 km.). The rabbinic injunction has reduced this to 1,2 km. You, the reader, are already aware that the emanations נצח, הוד, יסוד of the עולם העשיה unite with the emanations חסד, גבורה and תפארת. A חלל, vacuum is created by such a union. The numerical value of the word חלל is the same as the numerical value of the word חיים, life. This is an allusion to the disappearance or removal of the "life" of the קליפות (on the Sabbath). You have already learned that these קליפות had their hold on life exclusively in the region which has now become a vacuum by the union of the above-mentioned emanations; only death remains for these קליפות. Anyone performing work of the forbidden categories on the Sabbath thereby fills the vacuum and enables the קליפות to regain access to the three domains of of נצח, הוד and יסוד. Each of these domains represents one פרסה (4,8 km). The emanation מלכות is also included with them. Every פרסה consists of 4 מילין giving us a total of 12 מילין. In earlier times when the קליפות had not yet attained such predominance in our society, a person was permitted to walk on the Sabbath as far as the biblical limits, i.e. 14,4 km. Since the destruction of the Holy Temple -proof of the pervading influence of the קליפות which had penetrated into half the domain of נצח- the Rabbis decided to restrict the domain we can walk in on the Sabbath. This was alluded to in the words of the prophet Samuel (Samuel I 15,29) when he upraided Saul about not having killed Agag, king of the Amalekites: וגם נצח ישראל לא ישקר, "the domain of Netzach will not be forfeited by Israel." [My translation, to accommodate this רמז of the Ari zal. Ed.] Samuel only promised that Israel would not forfeit the entire domain of נצח. He did not promise that half of it would not be forfeited.
