It is with immense pleasure that we will now explore the wonders of His divine supervision with regards to the tikun of Noach, necessitating his gilgul (reincarnation) into Moshe. In Sha’ar HaPesukim (Shemos), the Arizal reveals that the generation of the mabul was comprised of holy neshamos that became corrupt. Now, HKB”H wants the world to achieve a state of tikun, as it is written (Shmuel II 14, 14): "וחשב מחשבות לבלתי ידח ממנו נידח"—He ponders thoughts (devises means), so that no one will be banished from Him. Therefore, He arranged for those corrupted neshamos to reincarnate into the neshamos of Yisrael in Mitzrayim. By means of the suffering they endured in Mitzrayim, they were purified in the “iron crucible.” Subsequently, they departed Mitzrayim, received the Torah and rectified the flaws of the generation of the mabul.
Based on this premise, the Arizal explains the specific sufferings that Bnei Yisrael were subjected to by Pharaoh. For instance (Shemos 1, 22): "כל הבן הילוד היאורה תשליכוהו"—every male child that will be born, you shall throw him into the river. Just as they were punished for their sins by water during the generation of the mabul; so, too, they were subjected to punishment by water in Mitzrayim. In Mitzrayim, however, a significant percentage achieved tikun through other forms of suffering and by ultimately receiving the Torah. This is the gist of his sacred teaching.
This coincides magnificently with the Arizal’s assertion that Noach himself reincarnated into Moshe in order to correct his own flaws. Therefore, to make amends for not having rebuked the people of his generation in the generation of the mabul, HKB”H arranged for that generation to reincarnate into Yisrael in Mitzrayim. Thus, they would achieve their tikun with the assistance of Noach’s gilgul, Moshe, who would take them out of Mitzrayim, give them the Torah, rebuke them, and guide them in the ways of the Torah.
Additionally, to rectify Noach’s second flaw—his failure to pray for the generation of the mabul and save them from extermination—Moshe jeopardized his own life to save Yisrael—the reincarnations of the generation of the mabul—from annihilation after the “cheit ha’eigel.” Thus, we see how the reunion and tikunim of these two gilgulim—the gilgul of Noach into Moshe and the gilgul of the generation of the mabul into Bnei Yisrael—go hand in hand magnificently.
