1 Chronicles 2:3

And Judah saw there a daughter of a certain Canaanite whose name was Shua; and he took her and went in to her.

But Er, Judah’s firstborn, was evil in the sight of Yahweh, so Yahweh put him to death.

Now these are the names of the sons of Israel—of Jacob and his sons—who were coming to Egypt: Reuben, Jacob’s firstborn.

And the sons of Judah according to their families were: of Shelah, the family of the Shelanites; of Perez, the family of the Perezites; of Zerah, the family of the Zerahites.

The sons of Judah were Perez, Hezron, Carmi, Hur, and Shobal.

And Judah was the father of Perez and Zerah by Tamar, and Perez was the father of Hezron, and Hezron was the father of Ram.
