You shall bring forward your brother Aaron, with his sons, from among the Israelites, to serve Me as priests, Aharon, Nadav and Avihu, Elazar and Itamar, the sons of Aharon: You already know that there is no sacrifice sacrificed without priests, Levites and Israelites, since they correspond to the three forefathers. Priests are from Chesed (Kindness). Hence, they atone, as 'iniquity is atoned by kindness.' And it is written (Isaiah 1:18), "Be your sins like crimson, they can turn snow-white." Levites are from the power of Gevurah (<might]). hence,="" they="" are="" appointed="" over="" the="" song.="" and="" because="" they="" correspond="" to="" 'arms="" everlasting'="" (the="" mystical="" traits="" of="" <i="">Chesed and Gevurah, that which is proper with this one is disqualified with that one. It is like our Rabbis, may their memory be blessed, said in Chullin (24a:7), "That which is fit with the priests is disqualified with the Levites, that which is fit with the Levites is disqualified with the priests." The Israelites are from the power of Mercy, which is called the Holy Elder Israel. It is about this matter that our Rabbis, may their memory be blessed, said [that] the priests, the Levites, and the Israelites [are all] indispensable for the sacrifice. In the Book of the Zohar (source not found): The priests, the Levites and the Israelites were together in all of the shifts. They all stood over the sacrifice to connect it with connections and to bring down blessings to the worlds; the [Israelite] shifts with prayer, the priests with [the offerings of] His will and the Levites with song. The shifts would arouse it for that pure thought to go up, the priests would arouse the Right [side] to embrace it [and] the Levites would arouse the Left [side] with mercy to unify with it. It is like you say (Song of Songs 2:6), "His left hand was under my head." And like this, the aroma [of the sacrifice] may become intertwined, one with the other, to connect one with the other. And this spirit is that of the Wife with Her Husband, such that all of the other forces eat, benefit and grow from Them. We learned that they [thus] grow and arise. And all [this] is from the secret of Israelites, priests and Levites, as you can see (end of quote). And do not wonder how it is that Aharon came out of the power of the Levites which is the trait of strict Divine justice, since he is the opposite of their trait. As this is the way of the Holy One, blessed be He, may He be exalted. He brings out fire from water and water from fire; He brings out sweet water from salt water; and from the power of bitterness, there does He shine His wonder to refine.

מימינו אש דת למו, “at His right hand was a fiery law unto them.” That the right side is one which symbolises fondness we know from Song of Songs 2,6: וימינו תחבקני, “and His right hand embraces me.”

וילדה זכר, “and she gave birth to a male;” According to our author (quoting ספר התולדות), a woman’s body contains seven openings, three on her left side, three on her right side, and one in the center. If her husband’s semen enters via the openings on her right side it will produce a male child. If it enters through the openings on her left side, she will produce a female child. If it enters through the opening in her center she will produce either a hermaphrodite possessing both fully developed masculine and feminine organs, or neither of such organs that are fully developed. Her position in bed shortly after her husband’s ejaculating semen into her determines through which of these openings the semen travels. If she lies on her right side the degree of ritual contamination “evaporates” faster than if she had been lying on her left side; this is why she cannot resume marital relations with have husband or offer her respective sacrifices until this process has run its natural cause. Lying on her left side at that critical juncture slows down the ritual contamination which was the result of the mother having been impregnated with her partners’ semen. This is why the Torah decreed different length of 33 or 66 days before the mother can purify herself. (verses 47) The above is hinted at by Solomon in Song of Songs 2,6: שמאלו תחת לראשי, “with his left hand under my head.” The maid’s lover did this in order to help his partner to give birth to males. [The fact that Solomon who had so many wives and concubines produced only a single male heir is proof that G-d’s active providence overrides nature. Ed.]
