Levítico 16:16 Cabalá: Sha'arei Orah

The secret of this has already been explained to you, which is that this refers to the Sanctuary-Heichal-היכל within which HaShem-יהו״ה, blessed is He, dwells. HaShem-יהו״ה, blessed is He, thus tells the Jewish people, take my dwelling within which I dwell, and I shall never depart from you. Even though you may become impure, my Indwelling Presence (Shechinah) shall not separate from you. This is as written,¹¹⁵Leviticus 16:16 “that dwells with them (HaShochen Eetam-השוכן אתם) amid their impurities.” Thus, when HaShem-יהו״ה, blessed is He, gave the Jewish people this gift, and the Indwelling Presence of HaShem-יהו״ה dwelt within them, all the treasuries of HaShem-יהו״ה, blessed is He, all His storehouses and chambers, and all bestowals of beneficence and emanations of blessings, were given into the hands of the Jewish people.

Rabbi Meir says:¹²⁸See Midrash Lekach Tov, Numbers 35:34 (our versions cite Rabbi Nathan). This is analogous to a king who tells his servant, if you seek me, you will find me with my son, as it states,¹²⁹Leviticus 16:16 “That dwells with them (HaShochen Itam-השוכן אתם) amid their impurities.” That is, even “if they contaminate My Dwelling (Mishkanee-משכני) that is within them.” Similarly, it states,¹³⁰Numbers 5:3 “They shall not contaminate their camps, within which I dwell (Shochen-שכן).”
