1 Chronicles 23:6-13

6And David organized them in divisions corresponding to the sons of Levi: Gershon, Kohath, and Merari.

7The sons of Gershon were Ladan and Shimei.

8The sons of Ladan: Jehiel the chief, and Zetham, and Joel, three.

9The sons of Shimei: Shelomoth, Haziel, and Haran, three. These were the heads of the fathers' houses of Ladan.

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

11Jahath was the chief, and Zizah the second; but Jeush and Beriah did not have many sons, therefore they became counted as a single father's house.

12The sons of Kohath: Amram, Izhar, Hebron, and Uzziel, four.

13The sons of Amram: Aaron and Moses. Aaron was set apart to dedicate the most holy things, that he and his sons forever should make offerings before the Lord and minister to him and pronounce blessings in his name forever.
