You shall prepare you the way, and divide the borders of your land, which the LORD your God causes you to inherit, into three parts, that every manslayer may flee there.
I commanded you at that time, saying, the LORD your God has given you this land to possess it: you shall pass over armed before your brothers the children of Yisra'el, all the men of valor.
that by two immutable things, in which it is impossible for God to lie, we may have a strong encouragement, who have fled for refuge to take hold of the hope set before us.
