Numbers 32:2 Save Caleb the son of Jephunneh the Kenezite, and Joshua the son of Nun: for they have wholly followed the LORD. (Jephunneh was Caleb's father )
Joshua 15:16-16 [15:16] And Caleb said, He that smiteth Kirjath-sepher, and taketh it, to him will I give Achsah my daughter to wife. [15:17] And Othniel the son of Kenaz, the brother of Caleb, took it: and he gave him Achsah his daughter to wife. (Achsah was the daughter of Caleb, and as Caleb was the son of Jephunneh [Numbers 32:2] , perhaps Othniel was Caleb's half-brother, i.e. Caleb & Othniel had the same mother?)
Judges 3:9 And when the children of Israel cried unto the LORD, the LORD raised up a deliverer to the children of Israel, who delivered them, even Othniel the son of Kenaz, Caleb's younger brother .
I Chronicles 4:15 And the sons of Caleb the son of Jephunneh; Iru, Elah, and Naam : and the sons of Elah, even Kenaz. (Caleb's father was Jephunneh, Caleb's sons were Iru, Elah, & Naam, and Caleb's grandson was Kenaz)
