Exodus 6:18

And the sons of Kohath, Amram, and Izhar, and Hebron, and
Uzziel
So they are reckoned in ( 1 Chronicles 6:18 ) though only the family of the Hebronites are mentioned in ( Numbers 26:58 )

and the years of the life of Kohath were one hundred and thirty three
years.
A Jewish chronologer says ^F6 he died one hundred years before the going out of Egypt: just the same number of years is ascribed to him by Polyhistor from Demetrius, an Heathen historian ^F7.
