Deuteronomy 19:8 (WEB)
Context Reading
6Otherwise, the avenger of blood might pursue the man slayer while hot anger is in his heart and overtake him, because the way is long, and strike him mortally, even though he was not worthy of death, because he didn’t hate him in time past. 7Therefore I command you to set apart three cities for yourselves. 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.
