1 Chronicles 2:3-6

The sons of Judah: Er, Onan, and Shelah; the three were born to him by Shua’s daughter the Canaanitess. Er, Judah’s eldest, was evil in the LORD’S sight, and He put him to death. Tamar, Judah’s daughter-in-law, bore him Perez and Zerah. Judah’s sons were five in all. [Gen 38] The sons of Perez: Hezron and Hamul. The sons of Zerah: Zimri, Ethan, Heman, Calcol, and Dara—five in all. [1 Kin 4:31]
