Numbers 35:33-34

Leeser(i) 33 And ye shall not defile the land wherein ye are; for the blood it is which defileth the land: and no atonement can be made unto the land for the blood which hath been shed therein, except through the blood of him that hath shed it. 34 And ye shall not render unclean the land which ye inhabit, in the midst of which I dwell; for I the Lord dwell in the midst of the children of Israel.
