I 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 transgressed in the accursed thing. The son of Ethan was Azariah. Also the sons of Hezron who were born to him were Jerahmeel, Ram, and Chelubai. Ram begot Amminadab, and Amminadab begot Nahshon, leader of the children of Judah
