1 Chronicles 2:15-19

Ozem, the sixth, and David, the seventh.

Their sisters were Zeruiah and Abigail. And the three sons of Zeruiah were Abshai, Joab, and Asahel.

Abigail gave birth to Amasa, and the father of Amasa was Jether the Ishmaelite.

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

When Azubah died, Caleb married Ephrath, who bore to him Hur.
