Numbers 35:11-24
11 select some towns to be your cities of refuge, to which a person who has killed someone accidentally may flee.
12 They will be places of refuge from the avenger, so that a person accused of murder may not die before he stands trial before the assembly.
13 These six towns you give will be your cities of refuge.
14 Give three on this side of the Jordan and three in Canaan as cities of refuge.
15 These six towns will be a place of refuge for Israelites, aliens and any other people living among them, so that anyone who has killed another accidentally can flee there.
16 “‘If a man strikes someone with an iron object so that he dies, he is a murderer; the murderer shall be put to death.
17 Or if anyone has a stone in his hand that could kill, and he strikes someone so that he dies, he is a murderer; the murderer shall be put to death.
18 Or if anyone has a wooden object in his hand that could kill, and he hits someone so that he dies, he is a murderer; the murderer shall be put to death.
19 The avenger of blood shall put the murderer to death; when he meets him, he shall put him to death.
20 If anyone with malice aforethought shoves another or throws something at him intentionally so that he dies
21 or if in hostility he hits him with his fist so that he dies, that person shall be put to death; he is a murderer. The avenger of blood shall put the murderer to death when he meets him.
22 “‘But if without hostility someone suddenly shoves another or throws something at him unintentionally
23 or, without seeing him, drops a stone on him that could kill him, and he dies, then since he was not his enemy and he did not intend to harm him,
24 the assembly must judge between him and the avenger of blood according to these regulations.
