1 Chronicles 4:13

“And the sons of Kenaz, etc.] Who was either the son of Chelub, or of Eshton: Othniel, and Seraiah; the first of these is he who is mentioned, (<061517>Joshua 15:17 <070113>Judges 1:13 3:9) and was the first judge in Israel: and the son of Othniel, Hathath; and the next mentioned.”

“the sons of Kenaz--the grandfather of Caleb, who from that relationship is called a Kenezite (Num 32:12).”

“4:13-15 The name Kenaz also appears as a descendant of Esau by Eliphaz (Gen 36:11); his descendants are known as the Kenizzites. The Kenizzites lived in the southern part of the land and had affiliations with Judah and Edom. Caleb son of Jephunneh was a Kenizzite (Num 32:12; Josh 14:6) and had a brother named Kenaz (Josh 15:17), whose family is listed here.”

“Kenaz: Jos 15:17; Jdg 1:13, Jdg 3:9-11 Hathath: or, Hathath and Meonathai, who begat, etc 1 Chronicles 4:14”

“Descendants of Kenaz. - קנז is a descendant of Hezron the son of Pharez, as may be inferred from the fact that Caleb the son of Jephunneh, a descendant of Hezron's son Caleb, is called in Num 32:12 and Jos 14:6 קנזּי, and consequently was also a descendant of Kenaz. Othniel and Seraiah, introduced here as קנז בּני, are not sons (in the narrower sense of the word), but more distant descendants of Kenaz; for Othniel and Caleb the son of Jephunneh were, according to Jos 15:17 and Jdg 1:13, brothers. (Note: The words used in Jdg 1:13, cf. Jos 15:17, of the relationship of Othniel and Caleb, הקּטון כלב אחי בּן־קנז, may be, it is true, taken in different senses, either as signifying filius Kenasi…”
