Kabbalah su Giobbe 38:13

Rise, Faithful Shepherd, for surely whoever studies Halachah [Halacha corresponds to Malchut], not for its own sake, and understands the Halachah, surely it is seized by him. Yet it has been explained that man should always study Torah even if not for its own sake, so that from studying not for its own sake it shall become for its own sake. And this Halachah is from the aspect of the good lad [This refers to Metatron] who separated from the Tree of Knowledge of Good and Evil, which comprises the forbidden and the permissible, the unclean and the clean, the fit and the unfit. After, the lad is called a girl, נַעֲרָה, by whom it will be fulfilled, "that the wicked might be shaken out of it, וְיִנָּעֲרוּ" (Job 38:13). These are the forbidden, the unclean and unfit, Samael and his legions.

Therefore, in the verse, "That you shall not take a wife to my son," what is meant by "my son"? All the souls in the world that come from the river which flows out from Eden, Which is Yesod, are the children of the Holy One, blessed be He. Therefore, "that you shall not take a wife," means a body; "to my son" refers to the soul; "of the daughters of the Canaan," are the bodies of the heathen nations, which the Holy One, blessed be He, will shake out of the Holy Land. As it is written, "That the wicked might be shaken out of it" (Iyov 38:13), as dirt is shaken out of a garment.
