Deuteronomy 4:42; Deuteronomy 9:28; Deuteronomy 19:4; Deuteronomy 28:55

42 that a manslayer might flee there, who unintentionally slew his neighbor without having enmity toward him in time past; and by fleeing to one of these cities he might live:

28 'Otherwise the land from which You brought us may say, "Because the LORD was not able to bring them into the land which He had promised them and because He hated them He has brought them out to slay them in the wilderness."

4 "Now this is the case of the manslayer who may flee there and live: when he kills his friend unintentionally , not hating him previously -

55 so that he will not give even one of them any of the flesh of his children which he will eat, since he has nothing else left, during the siege and the distress by which your enemy will oppress you in all your towns.
