Kabbalah sa Isaias 63:12: Zohar

AND MOSES WENT AND SPAKE THESE WORDS UNTO ALL ISRAEL. R. Hizkiah cited here the verse: “That caused his glorious arm to go at the right hand of Moses, that divided the water before them” (Isa. 63, 12). ‘Happy’, he said, ‘are Israel in that God chose them, and because He chose them He called them sons, firstborn, holy, brothers, and came down to dwell among them and sought to establish them after the supernal pattern, and spread over them seven clouds of glory.

Three holy brethren accompanied them, Moses, Aaron and Miriam, and for their sakes God gave them precious gifts. All the days of Aaron the clouds of glory did not depart from Israel, and Aaron, as we have stated, was the right hand of Israel, and therefore it is written, “that caused his glorious arm to go at the right hand of Moses”: this refers to Aaron.

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.
