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!”

Then Judah said to Onan, “Sleep with your brother’s wife. Perform your duty as her brother-in-law and produce offspring for your brother.”

When Judah and his brothers reached Joseph’s house, he was still there. They fell to the ground before him.

“What can we say to my lord?” Judah replied. “How can we plead? How can we justify ourselves? God has exposed your servants’ iniquity. We are now my lord’s slaves—both we and the one in whose possession the cup was found.”

Judah, your brothers will praise you.
Your hand will be on the necks of your enemies;
your father’s sons will bow down to you.
