Deuteronomy 19:1-3

World English Bible

19 When Yahweh your God cuts off the nations whose land Yahweh your God gives you, and you succeed them and dwell in their cities and in their houses, ² you shall set apart three cities for yourselves in the middle of your land, which Yahweh your God gives you to possess. ³ You shall prepare the way, and divide the borders of your land which Yahweh your God causes you to inherit into three parts, that every man slayer may flee there.
