1 Chronicles 2:4-8

Later Judah had twin sons from Tamar, his widowed daughter-in-law. Their names were Perez and Zerah. So Judah had five sons in all. The sons of Perez were Hezron and Hamul. The sons of Zerah were Zimri, Ethan, Heman, Calcol, and Darda—five in all. The son of Carmi (a descendant of Zimri) was Achan, who brought disaster on Israel by taking plunder that had been set apart for the LORD. The son of Ethan was Azariah.
