Numbers 35:15–21

15 These six cities shall be for refuge for the people of Israel, and cfor the stranger and for the sojourner among them, that anyone who kills any person without intent may flee there.

16 d“But if he struck him down with an iron object, so that he died, he is a murderer. The murderer shall be put to death. 17 And if he struck him down with a stone tool that could cause death, and he died, he is a murderer. The murderer shall be put to death. 18 Or if he struck him down with a wooden tool that could cause death, and he died, he is a murderer. The murderer shall be put to death. 19 eThe avenger of blood shall himself put the murderer to death; when he meets him, he shall put him to death. 20 And if he pushed him out of hatred or hurled something at him, flying in wait, so that he died, 21 or in enmity struck him down with his hand, so that he died, then he who struck the blow shall be put to death. He is a murderer. eThe avenger of blood shall put the murderer to death when he meets him.
