John Gill Commentary 1 Chronicles 23:9

"The sons of Shimei: Shelomoth, and Haziel, and Haran, three. These were the heads of the fathers` [houses] of Ladan." — 1 Chronicles 23:9 (ASV)

The sons of Shimei
Not him that was the son of Gershon, but a descendant of Laadan, his son, as Kimchi observes:

Shelomith, and Haziel, and Haran, these were the chief of the fathers
of Laadan ;
of the families that sprang from him.
