1st Chronicles 23:8

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.

10 And the sons of Shimei were, Jahath, Zina, and Jeush, and Beriah. These four were the sons of Shimei.

11 And 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.
