1 Chronicles 23:2-6

KJ2000(i) 2 And he gathered together all the princes of Israel, with the priests and the Levites. 3 Now the Levites were numbered from the age of thirty years and upward: and their number, man by man, was thirty and eight thousand. 4 Of which, twenty and four thousand were to look after the work of the house of the LORD; and six thousand were officers and judges: 5 Moreover four thousand were gatekeepers; and four thousand praised the LORD with the instruments which I made, said David, for praise. 6 And David divided them into divisions among the sons of Levi, namely, Gershon, Kohath, and Merari.
