1 Chronicles 23:6-13

6And David divided them into courses according to the sons of Levi: Gershon, Kohath, and Merari.

7Of the Gershonites: Laadan and Shimei.

8The sons of Laadan: the head was Jehiel, and Zetham, and Joel, three.

9The sons of Shimei: Shelomith, and Haziel, and Haran, three. These were the chief fathers of Laadan.

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

11And Jahath was the head, and Ziza the second; and Jeush and Beriah had not many sons: as father's house, therefore, they were reckoned as one.

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

13The sons of Amram: Aaron and Moses. And Aaron was separated, that he should be hallowed as most holy, he and his sons for ever, to offer before Jehovah, to do service to him, and to bless in his name for ever.
