Numbers 35:19-32 - Laws About Murder And Accidental Killing
19 The judge of blood shall slay the murderer, as soon as he findeth him. 20 "'If he thrust him of hate, or hurl at him with laying of wait that he die, 21 or smite him with his hand of envy that he die; he that smote him shall die, for he is a murderer. The justice of blood shall slay him as soon as he findeth him.
22 But and if he pushed him by chance and not of hate, or cast at him with any manner of thing and not of laying of wait, 23 or cast any manner of stone at him that he die therewith, and saw him not, and he cast it upon him and he died, but was not his enemy, neither sought him any harm; 24 then the congregation shall judge between the slayer and the executer of blood in such cases. 25 And the congregation shall deliver the slayer out of the hand of the judge of blood, and shall restore him again unto the franchised city whither he was fled. And he shall bide there unto the death of the high priest which was anointed with holy oil.
26 "'But and if he came without the borders of his privileged city whither he was fled, 27 if the blood avenger find him without the borders of his free town, he shall slay the murderer and be guiltless, 28 because he should have bidden in his free town until the death of the high priest, and after the death of the high priest, he shall return again unto the land of his possession. 29 And this shall be an ordinance and a law unto you, among your children after you in all your habitations.
30 Whosoever slayeth, shall be slain at the mouth of witnesses. For one witness shall not answer against one person to put him to death. 31 Moreover ye shall take none amends for the life of the murderer, which is worthy to die: But he shall be put to death. 32 Also ye shall take none atonement for him that is fled to a free city, that he should come again and dwell in the land before the death of the high priest.
