And you shall come to the Priests the Levites… (Ibid. 17:9) “The Priests the Levites” – for all Supernal Outflow comes in two aspects: Love and Limitation.², correspond to the Sefiros of the right, which convey the downward flow of love (Chesed), whereas the Levites correspond to the Sefiros of the left, which represent the forces of limitation (Tzimtzum). Love, on account of which G-d bestows upon the lower world, and the aspect of Limitation, which is that very Outflow which descends from the upper world to serve the lower world. Ohr Torah, Shemos. Likutey Amorim p.9b
