Caleb the son of Jephunneh - We have already met with this eminent person in Numbers 13:6, Numbers 13:30; Numbers 14:24, and elsewhere; and seen his courageous piety and inflexible integrity. The Targum says here, "They called him Caleb, the son of Jephunneh, because he had purged his soul from the counsel of the spies.
And the sons of Caleb the son of (f) Jephunneh; Iru, Elah, and Naam: and the sons of Elah, even Kenaz.
(f) Called also Esrom.
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, Joshua 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 Numbers 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.
Of Iru, Elah, and Naam, the sons of Caleb the son of Jephunneh (cf. on 1-Chronicles 4:13), nothing more is known. To connect Elah with the Edomite chief of that name (1-Chronicles 1:52) is arbitrary. Of Elah's sons only "and Kenaz" is mentioned; the ו copul. before קנז shows clearly that a name has been dropped out before it.
