Deuteronomy 19:4-10

CAB(i) 4 And this shall be the ordinance of the manslayer who shall flee there, and shall live, whosoever has killed his neighbor ignorantly, seeing that he did not hate him in times past. 5 And whoever shall enter with his neighbor into the thicket, to gather wood, if the hand of him that cuts wood with the ax should be violently shaken, and the axhead should fall off from the handle and strike his neighbor, and he should die, then he shall flee to one of these cities, and live. 6 Lest the avenger of blood pursue after the manslayer, because his heart is hot, and overtake him, if the way be too long, and kill him, though there is to this man no sentence of death, because he did not hate him in times past. 7 Therefore I command you, saying, You shall separate for yourself three cities. 8 And if the Lord shall enlarge your borders, as He swore to your fathers, and the Lord shall give to you all the land which He said he would give to your fathers; 9 if you shall hearken to do all these commands which I charge you this day, to love the Lord your God, to walk in all His ways continually, you shall add for yourself yet three cities to these three. 10 So innocent blood shall not be spilled in the land which the Lord your God gives you to inherit, and there shall not be in you one guilty of blood.
