1 Chronicles 26:23 -

The chiefs of the preceding two verses were introduced as descendants of Gershon through his son Laadan. The four names of this verse would seem to stand collectively for that of their father Kohath. One might, under these circumstances, have looked for the name of some member of each of these sub-families to appear in the number of the treasure-keepers just about to be mentioned. This is not so. Yet among other officials, and before the end of the general subject, the Izharites ( 1 Chronicles 26:29 ) and the Hebronites ( 1 Chronicles 26:30 , 1 Chronicles 26:31 ) do appear. This may possibly explain the mapping out thus of the Kohath family.
