Deuteronomy 19:1-3

AKJV(i) 1 When the LORD your God has cut off the nations, whose land the LORD your God gives you, and you succeed them, and dwell in their cities, and in their houses; 2 You shall separate three cities for you in the middle of your land, which the LORD your God gives you to possess it. 3 You shall prepare you a way, and divide the coasts of your land, which the LORD your God gives you to inherit, into three parts, that every slayer may flee thither.
