Numbers 35:33-34 ▼

33 So you shall not pollute the land in which you are; for blood pollutes the land, and no propitiation can be made for the land for the blood that is shed on it, except by the blood of him who shed it.

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