Coffman Commentaries on the Bible - 1 Chronicles 23:7
THE SONS OF GERSHON"Of the Gershonites: Ladan and Shimei. The sons of Ladan: Jehiel the chief, and Zetham, and Joel, three. The sons of Shimei: Shelomoth, and Haziel, and Haran, three. These were the heads of the fathers' houses of Ladan. And the sons of Shimei: Jahash, and Zina, and Jeush, and Beriah. These four were the sons of Shimei. And Jahash was the chief, and Zizah the second: but Jeush and Beriah had not many sons; therefore they became a fathers' house in one reckoning." read more
