Numbers 35:33-34

American Standard Version

³³ 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. ³⁴ And thou shalt not defile the land which ye inhabit, in the midst of which I dwell: for I, Jehovah, dwell in the midst of the children of Israel.
