1 Chronicles 2:3-5

Judah. ³ The sons of Judah were Er, Onan, and Shelah. They were born to him by Shuah the Canaanite. Er, the firstborn of Judah, did what was evil in the sight of the Lord and he slew him. ⁴ Tamar, his daughter-in-law, bore him Perez and Zerah, so Judah had five sons in all.

⁵ The sons of Perez were Hezron and Hamul.
