1 Chronicles 2:3-9, 25-26

Judah had Er, Onan, and Shelah; their mother was Bathshua the Canaanite. Er, Judah’s firstborn, was so bad before GOD that GOD killed him. Judah also had Perez and Zerah by his daughter-in-law Tamar—a total of five sons. Perez had Hezron and Hamul; Zerah had Zimri, Ethan, Heman, Calcol, and Darda—five sons. Carmi had Achar, who brought doom on Israel when he violated a holy ban. Ethan’s son was Azariah. And Hezron had Jerahmeel, Ram, and Chelubai.

The sons of Jerahmeel, Hezron’s firstborn: Ram his firstborn, followed by Bunah, Oren, Ozem, and Ahijah. Jerahmeel had another wife whose name was Atarah; she gave birth to Onam.
