Numbers 35:33-34

331So you shall not defile the land in which you live; for blood defiles the land, and no atonement can be made for the land for the blood that is shed on it, except 2by the blood of the one who shed it.

34So you shall not 3defile the land in which you live, in the midst of which 4I dwell; for I the Lord am dwelling in the midst of the sons of Israel.’”
