⁶ David divided them into divisions according to the sons of Levi : Gershon , Kohath , and Merari . ⁷ Of the Gershonites were Ladan and Shimei . ⁸ The sons of Ladan were Jehiel the first and Zetham and Joel , three . ⁹ The sons of Shimei were Shelomoth and Haziel and Haran , three . These were the heads of the fathers' households of Ladan . ¹⁰ The sons of Shimei were Jahath , Zina , Jeush and Beriah . These four were the sons of Shimei . ¹¹ Jahath was the first and Zizah the second ; but Jeush and Beriah did not have many sons , so they became a father's household , one class . ¹² The sons of Kohath were four : Amram , Izhar , Hebron and Uzziel . ¹³ The sons of Amram were Aaron and Moses . And Aaron was set apart to sanctify him as most holy , he and his sons forever e , to burn incense before the Lord , to minister to Him and to bless in His name forever e .
