David divided them into courses among the sons of Levi. These are enumerated according to their fathers' houses, but no more of these are mentioned here than the 24,000 who were engaged in the work connected with the Lord's house. The fathers' houses of those Levites corresponded with the classes into which they (Josephus, 'Antiquities') as well as the priests were divided (see the notes at 1 Chronicles 24:20-31; 1 Chronicles 26:20-28).
