1 Chronicles 23:2-6

BBE(i) 2 And he got together all the chiefs of Israel, with the priests and the Levites. 3 And the Levites, all those of thirty years old and over, were numbered; and the number of them, by heads, man by man, was thirty-eight thousand. 4 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; 5 Four thousand were door-keepers; and four thousand gave praise to the Lord with the instruments which I made, said David, for giving praise. 6 And David put them into divisions under the names of the sons of Levi: Gershon, Kohath, and Merari.
