224. There are five groups in the mixed multitude. These are the Nefilim (fallen), the Giborim (mighty), the Anakim (giants), the Refaim (shades) and the Amalekites. Because of them, the small Hei fell from its place, NAMELY FROM BINAH. Bilaam and Balak come from the side of Amalek, because if you remove the letters Am from Bilaam and the letters Lak from Balak, you are left with Babylon (Heb. Bavel). "Therefore is the name of it called Babylon; because Hashem did there confound (Heb. balal) the language of all the earth" (Beresheet 11:9).
225. These are the ones who remained of those of whom it was said at the time of the flood, "And He destroyed every living substance" (Beresheet 7:23). Those who survived, THE KLIPAH OF AMALEK, from the time of the fourth exile - NAMELY THE EXILE OF EDOM - became the leaders (lit. heads) of the world, men of great power. THIS IS BECAUSE THIS KLIPAH IS CONSIDERED THE HEAD AND KETER OF THE KLIPOT. They became a means of violence toward Yisrael and of them, it is written at the time of the flood, "For the earth is filled with violence through them" (Beresheet 6:13). These are the Amalekites.
269. Those WHO COMMIT INCEST separate the UPPER Hei OF YUD HEI VAV HEI from the LOWER Hei OF YUD HEI VAV HEI, so that the Vav OF YUD HEI VAV HEI may not come between them, as it is written: "You shall not uncover the nakedness of a woman and her daughter" (Ibid. 17). THE UPPER HEI IS THE MOTHER AND THE LOWER HEI IS HER DAUGHTER. BECAUSE THE VAV CANNOT COME BETWEEN THEM AND ALLOW THE ABUNDANCE FROM THE MOTHER TO REACH THE DAUGHTER, THEY ARE BOTH HARMED AND DEJECTED, BECAUSE THE ACTS OF BLOCKING AND PREVENTING THIS ABUNDANCE FROM REACHING THE LOWER HEI IS CONSIDERED TO BE HER NAKEDNESS AS WELL. And THE MOTHER AND THE DAUGHTER are the upper Shechinah, NAMELY MOTHER, and the lower Shechinah, NAMELY HER DAUGHTER. DURING EXILE, THE REASON WHY THE VAV CANNOT COME BETWEEN THE UPPER AND LOWER HEI IS THAT the mixed multitude - which are the Nefilim, the Giborim, the Amalekites, the Refaim and the Anakim (WHOSE INITIALS SPELL NEGA RA, WHICH MEANS EVIL INFLICTION) - MIGHT COME FORTH AND RECEIVE THE ABUNDANCE FROM THAT VAV. THUS, the Holy One, blessed be He, WHO IS THE VAV, is not permitted to come between them. The secret of this issue LIES IN THE VERSE: "And the river shall be wasted and dried up" (Yeshayah 19:5). The abundance of the upper Hei, WHICH IS CALLED THE RIVER, shall be wasted and the lower Hei, WHICH DOES NOT RECEIVE THE ABUNDANCE, shall dry up. And ALL THIS IS for the purpose of not allowing the mixed multitude to nourish themselves from the Vav, which is the Tree of Life. Therefore, the Vav is not permitted between the UPPER Hei and the LOWER Hei at the time when the mixed multitude is between them, DURING EXILE, AT TIME OF EXILE WHEN THEY MIGHT COME AND DRAW SUSTENANCE FROM THEM.
