1 Chronicles 23:12 (KJV)

Of the Gershonites were, Laadan, and Shimei.

The sons of Laadan; the chief was Jehiel, and Zetham, and Joel, three.

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

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

And Jahath was the chief, and Zizah the second: but Jeush and Beriah had not many sons; therefore they were in one reckoning, according to their father's house.

The sons of Amram; Aaron and Moses: and Aaron was separated, that he should sanctify the most holy things, he and his sons for ever, to burn incense before the LORD, to minister unto him, and to bless in his name for ever.

Now concerning Moses the man of God, his sons were named of the tribe of Levi.

The sons of Moses were, Gershom, and Eliezer.

Of the sons of Gershom, Shebuel was the chief.

And the sons of Eliezer were, Rehabiah the chief. And Eliezer had none other sons; but the sons of Rehabiah were very many.
