1 Chronicles 2:21-24

21Later Hezron had sexual relations with the daughter of Makir, the father of Gilead. (He had married her when he was sixty years old.) She bore him Segub.

22Segub was the father of Jair, who owned twenty-three cities in the land of Gilead.

23(Geshur and Aram captured the towns of Jair, along with Kenath and its sixty surrounding towns.) All these were descendants of Makir, the father of Gilead.

24After Hezron’s death, Caleb had sexual relations with Ephrath, his father Hezron’s widow, and she bore to him Ashhur the father of Tekoa.
