Thematic Bible: Divided them into four classes

Of these, twenty-four thousand were to be overseers of the work of the house of the Lord, and six thousand were judges and men of authority Four thousand were door-keepers; and four thousand gave praise to the Lord with the instruments which I made, said David, for giving praise. And David put them into divisions under the names of the sons of Levi: Gershon, Kohath, and Merari.
