Arpachshad fathered Cainan, Cainan fathered Shelah, and Shelah fathered Eber.

After he fathered Cainan, Arpachshad lived 430 years and had other sons and daughters, and then died. Cainan lived 130 years and fathered Shelah. After he fathered Shelah, Cainan lived 330 years and had other sons and daughters, and then died.

When Shelah had lived 30 years, he fathered Eber.

After he fathered Eber, Shelah lived 403 years and had other sons and daughters.

After Samlah died, Shaul from Rehoboth by the river ruled in his place.

After Shaul died, Achbor's son Baal-hanan ruled in his place.

Then she bore yet another son and named him Shelah. Judah was living in Kezib when she bore him.

After this, Judah told his daughter-in-law Tamar, "Go live as a widow in your father's house until my son Shelah grows up." But he was really thinking, ""otherwise, Shelah might die like his brothers." So Tamar left and lived in her father's house.

So she took off her mourning apparel, covered herself with a shawl, and concealed her outward appearance. Then she went out and sat at the entrance of Enaim, which is on the way to Timnah, because she knew that even though Shelah had grown up, she wasn't being given to him as his wife.

"Your signet ring, cord, and the staff in your hand," she suggested. So he gave them to her, had sex with her, and she became pregnant by him. Then she got up and left. Later, she took off her shawl and put on her mourning clothes.

When Judah recognized them, he admitted, "She is more upright than I, because I never did give her my son Shelah." And he never had sex with her again.

Simeon's sons Jemuel, Jamin, Ohad, Jachin, Zohar, and Shaul, who was the son of a Canaanite woman;

and Judah's sons Er, Onan, Shelah, Perez, and Zerah. (Technically, Er and Onan had died in the land of Canaan.) Perez's sons were Hezron and Hamul.
