1 Chronicles 2:3-4

Judah’s sons were Er, Onan, and Shelah. A Canaanite woman, the daughter of Shua, was their mother. Judah’s first son, Er, did what the LORD said was wicked, so the LORD put him to death. Judah’s daughter-in-law Tamar gave birth to Perez and Zerah. Judah was the father, so Judah had five sons.
