Thematic Bible: Divided them into four classes

David said: Of these, twenty-four thousand are to supervise the work of Jehovah's Temple and six thousand are to be officials and judges. Four thousand are to be gatekeepers and four thousand are to praise Jehovah with musical instruments I have provided for that purpose. David divided the Levites into groups corresponding to the sons of Levi: Gershon, Kohath and Merari.
