Job 11:12 Cábala: Or Neerav & Baal HaSulam's Introduction to Zohar

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.

The spiritual worlds evolved to the reality of our physical world, where a person is born with a [spiritual] body (the desire to receive) and a soul (the desire to give), a time of decay and a time of rebuilding (tikun). The [spiritual] body, the desire to receive for oneself, which has its roots in the thought of creation, travels through the system of impurity, as it is written "man is born a wild donkey", and remains subservient to this system until the age of thirteen. This is the time (under thirteen) of [spiritual] decay (because the person is mostly thinking of himself).
