From STEPBible's TIPNR genealogy data. A relationship the data marks uncertain is not shown here.

1 Chronicles 23:10 And the sons of Shimei: Jahath, Zina, Jeush, and Beriah. These were the sons of Shimei—four in all.
1 Chronicles 23:11 Jahath was the first and Zizah was the second; but Jeush and Beriah did not have many sons, so they were counted as one family and received a single assignment.
