Numbers 35:31-33 Moreover you shall take no satisfaction for the life of a murderer, which is guilty of death: But he shall surely be put to death.

TKJU⁽ⁱ⁾ ³¹ Moreover you shall take no satisfaction for the life of a murderer, which is guilty of death: But he shall surely be put to death. ³² And you shall take no satisfaction for him that is fled to the city of his refuge, that he should come again to dwell in the land, until the death of the priest. ³³ So you shall not pollute the land in which you are: For blood it defiles the land: And the land cannot be cleansed of the blood that is shed in it, but by the blood of him that shed it.
