3:14-39 This first phase of a two-stage registration of the tribe of Levi (see 4:34-49 for stage two) summarized each family group’s special responsibilities (described in greater detail in 4:1-33). This numbering was not linked with military duties, so it enrolled male Levites from the age of one month (3:40-41). • Three family groups are descended from Gershon, Kohath, and Merari, the three sons of Levi. These clans (often called the Gershonites, Kohathites, and Merarites) later inherited the “cities of refuge” (Josh 21) and filled various important posts in the Jerusalem Temple (2 Chr 29:3-17).
