Kabbalah sur Les Nombres 16:36

Let the deaf hear (Isa. 42:18) and the lame run and not get tired. Let the blind see (Isa. 42:18) the teeming visions (Exod. 38:8) which are gleaned and reaped by the heads of the tribes (Num. 30:2), they and their children (Gen. 33:6), commoner and priest alike, as is acknowledged properly. “All is foreseen, and permission is given” (Avot 3:16). Let the men go (Exod. 10:11) to the chief cornerstone (Ps. 118:22) to make books (Eccles. 12:12) which speak of the honor of God to the house of Israel. For all the congregation (Num. 16:3), the suckling with the venerable man (Deut. 32:25), and the mixed multitude fell a lusting (Num. 11:4) for Torah and testimony (Isa. 8:20), and the weaned child shall put his hand (Isa. 11:8).

How has become dim (Lam. 4:1) for them the candle of commandment and the light of Torah (Prov. 6:23) which gives light to these hypocrites. For like the grass they will soon wither (Ps. 37:2), since a mistake in learning causes intentional sin, Sheol and Abaddon (Prov. 15:11), the venom of serpents and the poison of vipers (Deut. 32:33). But they are altogether brutish and foolish (Jer. 10:8), [following] after vanity, and they will become naught (Jer. 2:5), attempting to bring forth a perverted justice (Hab. 1:4) which will eventuate in a defective deed. Turn away from the tents (Num. 16:26) of the man who slumbers, the ass of a wild man (Job 11:12); a fool and ignorant man is his companion, brutish, unlike a man (Prov. 30:2), who errs and is like a fool.

Division certainly applies to the left alone, as is written in relation to the second day: "And let it divide." (Ibid. 6) While of Korah, it is written: "Is it but a small thing to you, that the Elohim of Yisrael has separated you" (Numbers 16:9). It is also written: "At that time Hashem separated the tribe of Levi" (Deuteronomy 10:8). So, assuredly the separation appears only in the second day in the place of the left.
