This verse lists the Levitical cities given to the descendants of Aaron, the priests. These cities were designated as places of residence for the Levites who served in the temple and were also allocated to the priests for their livelihood. The allocation of these cities fulfilled the Lord's command to provide for the needs of the priests and Levites, ensuring the continuation of worship and service in the tabernacle and later the temple. This division of land among the Levites and priests demonstrated God's faithfulness in establishing order and provision for His chosen people.
