1 Chronicles 2:18-22

18Now Caleb the son of Hezron had sons by Azubah his wife, and by Jerioth; and these were her sons: Jesher, Shobab, and Ardon. 19When Azubah died, Caleb married Ephrath, who bore him Hur. 20Hur became the father of Uri, and Uri became the father of Bezalel.

21Afterward 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 became the father of Jair, who had twenty-three cities in the land of Gilead.
