Numbers: The entire chapter deals with the Levites. This tribe of Levi stems from his three sons: Gershon, Kohath and Merari. Aaron was descended of Kohath. All their posterity (Gershon, Kohath, Merari) are Levites but not all Levites are priests. Originally, after all the first-born of Egypt were killed the LORD wanted all the first-born (sons) set apart for Himself. He later changed that to just the tribe of Levi. While all the other tribes got designated land as an inheritance in Canaan. The LORD was the inheritance of the Levites.
