Numbers 35:33-34

Darby(i) 33 And ye shall not pollute the land wherein ye are; for blood, it polluteth the land; and there can be no atonement made for the land, for the blood that hath been shed therein, but by the blood of him that shed it. 34 And ye shall not defile the land that ye inhabit, in the midst whereof I dwell; for I am Jehovah who dwell in the midst of the children of Israel.
