So ye shall not pollute the land wherein ye [are:] for blood it defileth the land: and the land cannot be cleansed of the blood that is shed therein, but by the blood of him that shed it.
Berean Study Bible (BSB) - Numbers 35:33 >Do not pollute the land where you live, for bloodshed pollutes the land, and no atonement can be made for the land on which the blood is shed, except by the blood of the one who shed it.
