Joshua 20 - 22
Six cities of refuge are established (which are also among the cities given to the Levites), with 3 to the west of the Jordan, and 3 to the east, so that a person inaccurately accused of murder can flee to the closest one for refuge. Forty eight cities in all of Israel are given to the Levites, by their families. The men of Reuben, Gad, and half of Manasseh are released to return to their inheritance and families to the east of the Jordan, and they build a monument as a message to future generations that they also serve Jahweh, even though they live on the far side of the Jordan River.
