3 Now the Levites were numbered from the age of thirty years and upward: and their number by their polls, man by man, was thirty and eight thousand.
4 Of which, twenty and four thousand were to set forward the work of the house of the Lord; and six thousand were officers and judges:
5 Moreover four thousand were porters; and four thousand praised the Lord with the instruments which I made, said David, to praise therewith.
6 And David divided them into courses among the sons of Levi, namely, Gershon, Kohath, and Merari.
7 Of the Gershonites were, Laadan, and Shimei.
8 The sons of Laadan; the chief was Jehiel, and Zetham, and Joel, three.
9 The sons of Shimei; Shelomith, and Haziel, and Haran, three. These were the chief of the fathers of Laadan.
