After a long time Judah’s wife, the daughter of Shua, died. When Judah had finished mourning, he and his friend Hirah the Adullamite went up to Timnah to the sheepshearers.

Now Er, Judah’s firstborn, was evil in the Lord’s sight, and the Lord put him to death.

Judah’s sons: Er, Onan, Shelah, Perez, and Zerah; but Er and Onan died in the land of Canaan.
Perez’s sons: Hezron and Hamul.

Leah’s sons were Reuben (Jacob’s firstborn),
Simeon, Levi, Judah,
Issachar, and Zebulun.

Then Judah said to his daughter-in-law Tamar, “Remain a widow in your father’s house until my son Shelah grows up.” For he thought, “He might die too, like his brothers.” So Tamar went to live in her father’s house.

About three months later Judah was told, “Your daughter-in-law, Tamar, has been acting like a prostitute, and now she is pregnant.”

“Bring her out!” Judah said. “Let her be burned to death!”
