The tribe of Levi did not receive its own land. So chapter 35 explains how they received 48 towns spread out among the lands of the other tribes (see Joshua 21; see also Leviticus 25:32–34; 1 Chronicles 13:2; 2 Chronicles 11:14).
During the wilderness journey, the Levites lived in the center of the Israelite camp (compare Numbers 2:17). In the promised land, they were to live among the other tribes. Their presence was meant to influence the people for good (see Deuteronomy 33:9–10; 2 Chronicles 17:7–9; 19:8–11; 35:3).
These towns and their pasturelands were not a separate homeland (compare Numbers 18:23; 26:62). They were only a small portion of the land of Canaan, divided among the other tribes.
