The expansion of the גיד הנשה is the “מרכבה,” vehicle, of Samael in our world which touched, i.e. hurt, the thigh joint of Jacob. The Arizal explains Genesis 32, 26: וירא כי לא יוכל לו, ויגע בכף ירכו, "When he saw that he could not overpower him, he touched his thigh joint," as referring to Jacob's descendants. Samael, the guardian angel of Esau, left his mark on all the צדיקים, righteous people, who would stem from Jacob, i.e. any generation in which Jews would abandon their religion, etc. The words ותקע כף ירך יעקב, "Jacob's thigh joint was disjointed" (ibid.), are an allusion to the negative effect of the destruction of the Temple on this earth on the Celestial Regions. G–d swore an oath that He would not take up residence in the Jerusalem of the Heavenly Regions until the Jerusalem on earth had been restored and He would be able to take up residence there. This concept is known to us as "the name of G–d is not complete, neither is His throne complete, until matters on earth are developing to G–d's satisfaction."Put differently: "what happens down here is called גיד הנשה. The Talmud speaks about גזרות קשות כגידים, decrees as tough as sinews." The sinews referred to in such statements are the branches of the גיד הנשה. This גיד is the "evil" sinew of the 365 sinews in our bodies because it strengthens the power of Samael, i.e. the power of Esau. The damage to the Celestial Regions is done in a single "day." The word "day" in those regions is the one thousand years that Bereshit Rabbah 8, 2 describes as the length of G–d's day. [Because of this definition of "day," Adam could live almost one thousand years in terms of our days, though G–d had said he would die on the day he would eat from the fruit of the tree of knowledge. Ed.] The Zohar, commenting on Lamentations 1, 13: נתנני שוממה כל היום דוה, "He has made me desolate, I am in misery a whole day," states that this verse proves that when the destruction of the Temple was decreed, the exile was meant to last at least one thousand years.

Let me proceed to explain the nature of Benjamin's sanctity. Benjamin was on a loftier spiritual plane than his other brothers because he never bowed down to Esau who represented the סטרא דשמאלא, the left side of the diagram of emanations, the home of Samael. (At the time of the fateful encounter between Jacob and Esau he had not yet been born). The fact that his father Jacob bowed down to Esau cannot be held against Benjamin. The Zohar, commenting on the relevant verse in Genesis 33,3 (Sullam edition page 35), in which Jacob is described as prostrating himself before Esau seven times, writes as follows: "Rabbi Eliezer asked how Jacob, the choicest of the patriarchs, could contravene the injunction of the Torah in Exodus 34,14: 'do not prostrate yourself before any other deity for the Lord is a jealous G–d?' The answer given is that far from bowing down to the anti-G–d part that Esau represented, Jacob in fact prostrated himself before the שכינה, for we find at the beginning of the same verse: והוא עבר לפניהם, "It proceeded ahead of them." This excuse can be used only for Jacob, but not for his sons. The "11 stars," i.e. the other tribes bowed to Esau, not to the שכינה. The knees which bent to Esau, representative of Samael, were the cause that Samael succeeded in inflicting an injury on Jacob's thigh joint. That injury represented judgment מדה כנגד מדה, tit for tat, because Esau's thigh joint bore the imprint of the original serpent. We have pointed out that the Targum of יודע ציד, hunter, (Esau's profession) is נחשירכן. The Tziyoni reads this as two words נחש ירכן, seeing that the serpent's image [snake shaped birthmark? Ed.] was tattooed on Esau's thigh joint. We dealt with this in our commentary on Toldot. Because of this additional dimension of sanctity possessed by Benjamin even before his birth, G–d had prophesied to Jacob in 35, 11, ומלכים מחלציך יצאו, "Kings will emerge from your loins." People bending their knees to the kings from the tribe of Benjamin, will be the fitting contrast to the other tribes who had bent their knees to Esau instead. This stands out particularly in view of the list of kings descended from Esau that are listed in פרשת וישלח. I have mentioned that righteous Jewish kings represent the Kingdom of Heaven here on earth.
