דברי הימים א, פרק כ״ד, פסוק ל׳

The organization of the Levite families reaches its conclusion with a precise and structured system. Just like the priests, the Levites were organized into twenty-four distinct divisions to manage their duties. This structure was carefully distributed among the major Levite branches. Nine divisions came from the descendants of Gershon, eight from Kohath, and seven from Merari.

The historical record specifically names the sons of Mushi, including Mahli, Eder, and Jerimoth, to show that the names of these ancestral houses were faithfully preserved and remained unchanged over time. Ultimately, the broader categorization by ancestral houses serves to identify the individual members of the various families who made up these twenty-four working divisions [מצודת דוד].
