“So by command of the LORD the people of Israel gave to the Levites the following cities and pasturelands out of their inheritance” (v3). The Levites were priests and temple workers who lacked their own territory within Israel. When they weren’t serving at the Temple, they lived in designated towns inside other tribal territories, so that all Israel had contact with priests and all Israel shared ownership of the Temple and its workers. Without a king, Israel was unified by this dedication to the worship of God.
“And the Lord gave them rest on every side …” (v44). No other inheritance – houses or land or wealth – can compare to the security of a life centered on worshiping and obeying God.
