Rashi on Numbers 35:34/רש"י על במדבר ל״ה:ל״ד

1אשר אני שכן בתוכה [AND YE SHALL NOT DEFILE THE LAND] … IN WHICH I DWELL — It means: Do not do anything defiling to the land so that you will make Me dwell amidst its uncleanness,

2‎'כי אני ה שכן בתוך בני ישראל FOR I, THE LORD, DWELL AMONG THE CHILDREN OF ISRAEL — for even when they (the Israelites) are unclean My Shechinah remains amongst them (Sifrei Bamidbar 160:15).
