1 Chronicles 2:18-22

18Caleb the son of Hezron had children by Azubah, his wife, and by Jerioth. Now these were her sons: Jesher, Shobab, and Ardon.

19When Azubah died, Caleb took Ephrath as his wife, who bore him Hur.

20And Hur begot Uri, and Uri begot Bezalel.

21Now afterward Hezron went in to the daughter of Machir the father of Gilead, whom he married when he was sixty years old; and she bore him Segub.

22Segub begot Jair, who had twenty-three cities in the land of Gilead.
