1 Chronicles 23:11-13

Young's Literal Translation

¹¹ And Jahath is the head, and Zizah the second, and Jeush and Beriah have not multiplied sons, and they become the house of a father by one numbering.

¹² Sons of Kohath [are] Amram, Izhar, Hebron, and Uzziel, four.

¹³ Sons of Amram: Aaron and Moses; and Aaron is separated for his sanctifying the holy of holies, he and his sons -- unto the age, to make perfume before Jehovah, to serve Him, and to bless in His name -- unto the age.
