Numbers 35:30-34

ISV(i) 30 Capital Cases Require Multiple Witnesses“Every murderer of a human being is to be executed only according to testimony given by multiple witnesses. A single witness is not to result in a death sentence. 31 You are to receive no ransom for the life of a killer who is guilty of murder; instead, he is to die. 32 You are not to receive payment of a ransom for someone who had fled to a town of refuge but then left to live in his homeland before the death of the high priest. 33 You are not to pollute the land where you live, because blood defiles the land, and the land cannot atone for blood that has been spilled on it, except through the blood of the one who spilled it. 34 You are not to defile the land where you will be living, because I’m living among you. I am the LORD, who lives in Israel.”
