1 Chronicles 4:11-15

And Chelub the brother of Shuah begat Mehir, which was the father of Eshton.

And Eshton begat Beth-rapha, and Paseah, and Tehinnah the father of Ir-nahash. These are the men of Rechah.

And the sons of Kenaz; Othniel, and Seraiah: and the sons of Othniel; Hathath.

And Meonothai begat Ophrah: and Seraiah begat Joab, the father of the valley of Charashim; for they were craftsmen.

And the sons of Caleb the son of Jephunneh; Iru, Elah, and Naam: and the sons of Elah, even Kenaz.
