I Chronicles 4:15

And the sons of Caleb the son of Jephunneh,.... Jephunneh is not the same with Hezron, as the Targum, but another son of Kenaz, hence called the Kenezite, Jos 14:6 and brother of Othniel; and Caleb his son is the same that was sent one of the spies of the land of Canaan by Moses, see Num 13:6. his sons were Iru, Elah, and Naam; of whom we nowhere else read: and the sons of Elah, even Kenaz; another Kenaz, or rather it should be read Uknaz; so Jarchi and Kimchi.

In this chapter we have, I. A further account of the genealogies of the tribe of Judah, the most numerous and most famous of all the tribes. The posterity of Shobal the son of Hur (Ch1 4:1-4), of Ashur the posthumous son of Hezron (who was mentioned, Ch1 2:24), with something particular concerning Jabez (Ch1 4:5-10), of Chelub and others (Ch1 4:11-20), of Shelah (Ch1 4:21-23). II. An account of the posterity and cities of Simeon, their conquest of Gedon, and of the Amalekites in Mount Seir (v. 24-43).
