And the sons of Judah after their families were; of Shelah, the family of the Shelanites: of Pharez, the family of the Pharzites: of Zerah, the family of the Zarhites.

These were the descendants of Judah by their clans: The Shelanite clan from Shelah, the Perezite clan from Perez, and the Zerahite clan from Zerah.
