1 Chronicles 2:3-6

Judah had three sons from Bathshua, a Canaanite woman. Their names were Er, Onan, and Shelah. But the LORD saw that the oldest son, Er, was a wicked man, so he killed him. 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.
