5Moreover four thousand were porters; and four thousand praised the LORD with the instruments which I made, said David, to praise therewith. 6And David divided them into courses among the sons of Levi, namely, Gershon, Kohath, and Merari. 7Of the Gershonites were, Laadan, and Shimei. 8The sons of Laadan; the chief was Jehiel, and Zetham, and Joel, three.9The sons of Shimei; Shelomith, and Haziel, and Haran, three. These were the chief of the fathers of Laadan. 10And the sons of Shimei were, Jahath, Zina, and Jeush, and Beriah. These four were the sons of Shimei. 11And Jahath was the chief, and Zizah the second: but Jeush and Beriah had not many sons; therefore they were in one reckoning, according to their father's house.
