이사야 63:12의 Kabbalah

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.

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."
