7 The Gershonite family units were defined by their lines of descent from Libni and Shimei, the sons of Gershon. 8 Three of the descendants of Libni were Jehiel (the family leader), Zetham, and Joel. 9 These were the leaders of the family of Libni. Three of the descendants of Shimei were Shelomoth, Haziel, and Haran. 10 Four other descendants of Shimei were Jahath, Ziza, Jeush, and Beriah. 11 Jahath was the family leader, and Ziza was next. Jeush and Beriah were counted as a single family because neither had many sons.
