1 Chronicles 2:5-10

The sons of Perez were Hezron and Hamul. The sons of Zerah were Zimri, Ethan, Heman, Calcol and Dara; five of them in all. The son of Carmi was Achar, the troubler of Israel, who violated the ban. The son of Ethan was Azariah. Now the sons of Hezron, who were born to him were Jerahmeel, Ram and Chelubai. Ram became the father of Amminadab, and Amminadab became the father of Nahshon, leader of the sons of Judah
