“This is so that innocent blood will not be shed in the middle of your land which Yahweh your God gives you for an inheritance, leaving blood guilt on you.”
Deuteronomy 19:10 (WEB)
Context Reading
8If Yahweh your God enlarges your border, as he has sworn to your fathers, and gives you all the land which he promised to give to your fathers; 9and if you keep all this commandment to do it, which I command you today, to love Yahweh your God, and to walk ever in his ways, then you shall add three cities more for yourselves, in addition to these three. 10This is so that innocent blood will not be shed in the middle of your land which Yahweh your God gives you for an inheritance, leaving blood guilt on you. 11But if any man hates his neighbor, lies in wait for him, rises up against him, strikes him mortally so that he dies, and he flees into one of these cities; 12then the elders of his city shall send and bring him there, and deliver him into the hand of the avenger of blood, that he may die.
