Kabbalah su Isaia 63:78

For that reason {it is written}, "That caused His glorious arm to go at the right hand of Moses" (Isaiah 63:12), [This refers to Malchut], and "dividing the water" (Ibid.) by tearing the water into twelve pieces, the numerical value of Vav Vav. And by merit of {the letter} Aleph [the letter is found if you spell out the word Vav as Vav Aleph Vav] You turned the sea into dry land. In it the Egyptians drowned, who did not believe in the Vav, [This corresponds to Zeir Anpin] which is {the value} one. In the future to come it will be fulfilled in Israel, the seed of Abraham, "As in the days of your coming out of the land of Egypt I will show him marvelous things" (Micah 7:15). In you it shall be fulfilled, "That caused His glorious arm to go at the right hand of Moses, dividing the water" of the Torah, to make yourself, "an everlasting name" (Isaiah 63:12). There you shall attain your bride.

Now, the above is as scripture states⁴²Deuteronomy 32:18, “You have caused the Rock that bore you to be removed”. Moreover, it states⁴³Psalms 68:35, “Give strength to G-d”. This is in accordance to the statement⁴⁴Talmud Berachot 17, “Rabbi Yochanan says, ‘Happy is he who toils in Torah and brings satisfaction to the One who formed him.’ – meaning that he does not toil in the Torah in order to receive a reward at all. Rather, his intent is solely to bring satisfaction to the One who formed him, about whom it is written⁴⁵Isaiah 63:9, “In all their suffering, He suffered.” That is, wherever Israel were exiled the Shechinah went with them. She is our Mother, about whom it says⁴⁶Isaiah 50:1, “Thus says HaShem, ‘Where is your Mother’s bill of divorce [as proof] that I banished her? To which of my creditors did I sell you? Truly, you were sold through your sins and through your transgressions she was banished with you.’” [It is, specifically, the Shechinah that] is called “The One Who Formed us”, as in the verse⁴⁷Deuteronomy 32:18, “You have caused the Rock who bore you to be removed.” [The word for rock here is Tzoor (צור), which also means the “source of form”, just as a child is formed in its mother’s womb.] This is why [Rabbi Yochanan said that such a person brings satisfaction “to the One who formed him”, rather than saying “to the Holy One, Blessed is He.”

Rabbi Elazar said, "O, how great is Your goodness, which You have laid up for those who fear You" (Ps. 31:20). How great is the heavenly abundance that the Holy One, blessed be He, shall bestow on human beings; to those sin-fearing, divine, and righteous men who learn the Torah as they arrive at the World to Come. It is not only written, "Your goodness," but also "how great is Your goodness." And who is He? "The memory of Your goodness" (Ps. 145:7), which is the pleasure of life that is drawn from the World to Come down to the life of the Worlds. This is"the memory of your goodness," which is certainly "the great goodness toward the house of Yisrael" (Isaiah 63:7).

And now

It was through this small Hei, the Hei of Abraham, which is the letter Hei in BeHibar'am that Moses received assistance, and it is written of him: "That caused His glorious arm to go at the right hand of Moses" (Isaiah) 63:12). He took it from there (from among the kelipot) by the power of the letter Vav and brought it with him. Immediately, Yud-Hei rested on it and the vow was fulfilled: "For Yah has sworn by His throne (Heb. Kes, Caf-Samech) that Hashem will have war" (Shemot 17:16). What is "From generation to generation"? This is Moses, about whom it is written: "One generation passes away, and another generation comes..." (Kohelet 1:4). It has already been explained that one generation contains no fewer than 600,000. This refers to Moses, about whom it is said that one woman gave birth in Egypt to 600,000 in one belly (meaning Moshe, who equals 600,000 souls).

Rabbi Yitzchak analyzed the words: "He who caused His glorious arm to go at the right hand of Moses, that divided the water before them to make Himself an everlasting name" (Isaiah 63:12). He said that "His glorious arm" is the merit of Abraham, (who is the embodiment of Chesed) and who is to the right side of Moses, Tiferet of Moses. And, therefore, "that divided the water before them" indicates that the merit of Abraham divides the water. And for what reason? "To make Himself an everlasting name."

So whenever Judgment is upon the world, the Holy Spirit says, "Alas! There is no one like Moses." As it is written: "Then He remembered the days of Moses... Where is he who brought them up out of the sea...?" (Isaiah 63:11). The verse tells us, "Hashem said to Moses, 'Why do you cry to Me?'" (Shemot 14:15), showing that he himself brought them up out of the sea through prayer and because he prayed for Yisrael upon the sea, he was called "he who brought them up out of the sea," as he did bring them out from the sea.

Higher Eden and lower Eden
This Chochmah of the thirty-two paths is called Eden. This Eden flows from the most concealed highest Eden, which is the concealed brain. It is considered a beginning starting with this Eden, which is Chochmah of the thirty-two paths; that is, a beginning for shining on lower beings. For neither beginning nor end is considered in Atika, that is, in the concealed brain; beginning and end are supernal Chochmah and lower Chochmah. For the concealed brain does not shine on lower beings from itself; rather, its illumination is via Mazala and into the brain of the thirty-two paths, and that brain does have a beginning, since it contains Chochmah of the left column; and it does have an end, that is, Malchut that is called lower Chochmah, where this Chochmah can be revealed. And since Atika has neither beginning nor end, it is not called “you,” in the second person, but “he,” that is, the hidden third person. And the place that does contain a beginning, that is, Chochmah of the thirty-two paths, is called ‘you’ and ‘father,’ as written, “You… are our father” (Yeshayahu 63:16).
