¹ sn The chapter has four main parts to it: Kohathites (1-20), Gershonites (21-28), Merarites (29-33) and the census of the Levites (34-49).

¹ tn The disjunctive vav (ו) here introduces a new section, listing the various duties of the clan in the sanctuary. The Gershonites had a long tradition of service here. In the days of David Asaph and his family were prominent as musicians. Others in the clan controlled the Temple treasuries. But in the wilderness they had specific oversight concerning the tent structure, which included the holy place and the holy of holies.
