1 Chronicles 2:4-8

And Tamar his daughter in law bare him Pharez and Zerah. All the sons of Judah were five.

The sons of Pharez; Hezron, and Hamul.

And the sons of Zerah; Zimri, and Ethan, and Heman, and Calcol, and Dara: five of them in all.

And the sons of Carmi; Achar, the troubler of Israel, who transgressed in the thing accursed.

And the sons of Ethan; Azariah.
