The sons of Judah were: Er, Onan, and Shelah; these three Bathshua, a Canaanite woman, bore to him. But Judah’s firstborn, Er, was wicked in the sight of the Lord, so he took his life.
The descendants of Judah by their clans were: through Shelah, the clan of the Shelahites; through Perez, the clan of the Perezites; through Zerah, the clan of the Zerahites.
