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.
KJV
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.
ASV
So ye shall not pollute the land wherein ye are: for blood, it polluteth the land; and no expiation can be made for the land for the blood that is shed therein, but by the blood of him that shed it.
