Comentario citado sobre Isaías 54:6

The verse also contains an allusion to the כנסת ישראל, the Jewish people as a conceptual entity. We find that this term is applied to women in such verses as Isaiah 54,5: כי בעליך עושיך, "for He who has made you will espouse you;" the prophet also continues: ואשת נעורים, "and the wife of your youth;" the prophet Hoseah describes the relationship of G'd and כנסת ישראל in Hoseah 2,21: וארשתיך לי לעולם, (G'd speaking to His bride) "I will betroth Myself to you forever, etc." Isaiah 50,1: "where is the bill of divorce I have given you?" There are more such verses to be found scattered throughout the Books of the Prophets. וילדה זכר, "and she gives birth to a male child, etc." when viewed from a moral-ethical vantage-point, the Torah reveals that when the מזריע the initiative for the husband-wife relationship with G'd originates with the Jewish people, the כנסת ישראל, then the product of such an initiative will be a male child, זכר, the entire nation will attain the highest spiritual level. The word זכר, male, is hyperbole for the highest moral-ethical achievenment. In Sanhedrin 98 and Shemot Rabbah 15 the superiority of the ultimate redemption to the redemption at the time of the Exodus from Egypt is described. The ultimate redemption is perceived there as the corollary of Israel distinguishing itself by the performance of good deeds, etc. The prophet described the Exodus in terms of Israel being "naked and nude" (Ezekiel 16,7). Clothing is perceived as a layer of מצות and good deeds covering our bodies. The inadequacy of the Jewish people at the time of the Exodus is underlined in Deut. 4,34 where G'd describes the Exodus as wrenching one people from the midst of the same people, something that made it legally difficult for G'd to justify taking the Israelites out of Egypt when He did. That redemption has been described only in female terms and that is why it did not endure in the end and the Temple was destroyed. Not so the redemption of the future which will occur as a direct result of Israel's merits. First and foremost among those merits is Israel's preoccupation with Torah as described in Deut. 31,21 something that will never be forgotten even during a protracted period of exile. The Torah continues: וטמאה, the mother contracts ritual impurity as a result of giving birth. Here the Torah alludes to the way G'd initiates a process which culminates in the rehabilitation of Israel so that it will attain a spiritual level that qualifies for the description זכר. The "days" mentioned here are to be understood as seven years similar to Genesis 24,55 where Laban and his mother wanted Rebeccah to delay her departure by ימים, i.e. a year. The years which are viewed as the חבלי משיח, the birth-pangs of the Messiah, last for seven years during which Israel will be refined spiritually in preparation of his arrival. He will make his appearance during the eighth year. On the eighth day, at the beginning of the eighth day (year), the baby is to have its foreskin removed, i.e. the concept of a foreskin which acts as a barrier between man and G'd will be removed from the universe. We read in Zachariah 13,2 that G'd will destroy the spirit of impurity from the earth. This will occur during the eighth year. It is well known that conceptually the foreskin is identical with the forces of the קליפה, the spiritually negative emanations. When the Torah wrote the word וטמאה, describing the state of the mother, this is a simile for the afflictions experienced during the birth-pangs of the Messiah.

in her virginity Certain nouns in the Holy Tongue are never singular, like “juvenility” [Isaiah 54:6], “old age” [Genesis 37:3], “childhood” [cf .
