1 Chronicles 2:42

Now the sons of Caleb the brother of Jerahmeel ,.... Called Chelubai, 1 Chronicles 2:9 and is the same Caleb spoken of in 1 Chronicles 2:18 and his sons next reckoned were by a third wife, Azubah, Ephrath being dead, 1 Chronicles 2:19 and these sons were

Mesha his firstborn, which was the father of Ziph ; who gave name to the city of Ziph; there were two of this name in the tribe of Judah, Joshua 15:24 or this is the title of Mesha, governor of the city of Ziph; so the Targum calls him, prince of the Ziphites:

and the sons of Mareshah the father of Hebron ; according to Kimchi and Ben Melech, the words are to be supplied thus, "and the sons of Ziph were Mareshah the father of Hebron"; which, though sometimes the name of a city in the tribe of Judah, is here the name of a man, from whom, perhaps, the city had its name, since Hebron is said to have sons in the next verse; Jarchi makes Mesha to be the prince of Ziph, and prince of the children of Mareshah, and prince of Hebron.
