“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.”
Numbers 35:33 (BSB)
Context Reading
31You are not to accept a ransom for the life of a murderer who deserves to die; he must surely be put to death. 32Nor should you accept a ransom for the person who flees to a city of refuge and allow him to return and live on his own land before the death of the high priest. 33Do 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. 34Do not defile the land where you live and where I dwell. For I, the LORD, dwell among the Israelites.”
