1 Chronicles 2:21-24

21After some time, when Hezron was 60 years old, he married Makir's daughter. She was Gilead's sister. Hezron had sex with her and she gave birth to a son called Segub.

22Segub became the father of Jair. Jair ruled 23 towns in the region of Gilead.

23But later Geshur and Aram attacked Jair's towns and took them for themselves. They also took Kenath and the 60 small towns around it. All those people were descendants of Gilead's father, Makir.

24After Hezron died, Caleb married his father's widow, Ephrathah. She gave birth to a son for him. His name was Ashhur, and he became the father of Tekoa.
