Numbers 35:16-24

16‘1But if he struck him with an iron object, so that he died, he is a murderer; the murderer must be put to death. 17And if he struck him with a stone in the hand, by which he would die, and as a result he did die, he is a murderer; the murderer 2must be put to death. 18Or if he struck him with a wooden object in the hand, by which he would die, and as a result he did die, he is a murderer; the murderer must be put to death. 19The blood avenger himself shall put the murderer to death; he himself shall put him to death when he meets him. 20Now 3if he pushed him in hatred, or he threw something at him 45with malicious intent, and as a result he died, 21or if he struck him with his hand with hostility, and as a result he died, the one who struck him must be put to death; he is a murderer. The blood avenger shall put the murderer to death when he meets him.

22‘6But if he pushed him suddenly, without hostility, or threw any object at him without 7malicious intent, 23or had any 8deadly stone, and without looking he dropped it on him so that he died, while he was not his enemy nor was he seeking 9to harm him, 24then 10the congregation shall judge between the one who fatally struck the victim and the blood avenger in accordance with these ordinances.
