Parashas Metzora · Passuk 15:31
Chabad.org — English translation + Rashi
Torah Temima points to Toras Kohanim.
English: “By defiling My Mishkan” — this teaches that even though they are impure, the Shechinah is among them.
Shechinah amid impurity
Chazal explain the severity of the warning: the Shechinah remains among Israel even in their impurity, so defilement of the Mishkan is a direct affront to the Divine Presence still in their midst.
