Numbers 35:9-34

Then the LORD spoke to Moses, saying, “Tell the Israelites, ‘When you cross the Jordan [River] into the land of Canaan, then you shall select for yourselves cities to be cities of refuge, so that the one who kills any person unintentionally may escape there. The cities shall be to you as a refuge from the avenger, so that the one who has caused the death of another will not be killed until he has had a [fair] trial before the congregation. The cities which you are to provide shall be your six cities of refuge. You shall provide three cities on this [east] side of the Jordan [River], and three [more] cities in the land of Canaan; they are to be the cities of refuge. These six cities shall be a refuge for the Israelites and for the stranger and the resident alien among them; so that anyone who kills a person unintentionally may escape there. ‘But if he struck his victim down [intentionally] with an iron object so that he died, he is a murderer; the murderer shall certainly be put to death. If he struck his victim down [intentionally] with a stone in hand, which may cause a person to die, and he died, he is a murderer; the murderer shall certainly be put to death. Or if he struck his victim down [intentionally] with a wooden object in hand, which may cause a person to die, and he died, he is a murderer; the murderer shall certainly be put to death. The blood avenger shall himself put the murderer to death; he shall put him to death when he meets him. But if he pushed his victim out of hatred or threw something at him with malicious intent, and he died, or if, in enmity, he struck the victim down with his hand, and he died, the one that struck the victim shall certainly be put to death; he is a murderer. The blood avenger shall put the murderer to death when he meets him. ‘But if he pushed the victim suddenly, not in enmity, or threw anything at him without malicious intent, or without seeing him hit him [accidentally] with a stone object that could kill him, and he died, and [the offender] was not his enemy nor intending to harm him, then the congregation shall judge between the offender and the blood avenger according to these ordinances. The congregation shall rescue the offender from the hand of the blood avenger and return him to his city of refuge, [the place] to which he had escaped; and he shall live there until the death of the high priest who was anointed with the sacred oil. But if at any time the one guilty of manslaughter comes outside the border of his city of refuge to which he fled, and the blood avenger finds him outside the border of his city of refuge and kills the offender, the blood avenger will not be guilty of murder, because the offender should have remained in his city of refuge until the death of the high priest. But after the high priest’s death the offender shall return to the land of his possession. ‘These things shall be a statute for you throughout your generations wherever you may be. ‘If anyone kills a person [intentionally], the murderer shall be put to death on the testimony of [two or more] witnesses; but no one shall be put to death on the testimony of [only] one witness. Moreover, you shall not accept a ransom [in exchange] for the life of a murderer guilty and sentenced to death; but he shall certainly be put to death. You shall not accept a ransom for him who has escaped to his city of refuge, so that he may return to live in his [own] land before the death of the high priest. So you shall not pollute and defile the land in which you live; for [the shedding of innocent] blood pollutes and defiles the land. No atonement (expiation) can be made for the land for the [innocent] blood shed in it, except by the blood (execution) of him who shed it. You shall not defile the land in which you live, in the midst of which I live, for I, the LORD, live among the people of Israel.’ ”
