And Eshton begat Bethrapha
Or the family of Rapha:

and Paseah, and Tehinnah the father of Irnahash ;
or the city of Nahash; Tehinnah seems to have been the prince or governor of a city, so called:

these are the men of Rechah ;
these sons of Eshton dwelt in a place called Rechah; the Targum, without any reason, says, these are the men of the great sanhedrim.
