1 Chronicles 2:15-19

Ozem the sixth, David the seventh:

Whose sisters were Zeruiah, and Abigail. And the sons of Zeruiah; Abishai, and Joab, and Asahel, three.

And Abigail bare Amasa: and the father of Amasa was Jether the Ishmeelite.

And Caleb the son of Hezron begat children of Azubah his wife, and of Jerioth: her sons are these; Jesher, and Shobab, and Ardon.

And when Azubah was dead, Caleb took unto him Ephrath, which bare him Hur.
