6. Later, Judah chose Tamar as a wife for Er, his eldest son.
7. But Er was very evil, and the Lord took his life.
8. So Judah told Onan, “It's your duty to marry Tamar and have a child for your brother.”
9. Onan knew the child would not be his, and when he had sex with Tamar, he made sure that she would not get pregnant.
10. The Lord wasn't pleased with Onan and took his life too.
11. Judah did not want the same thing to happen to his son Shelah, and he told Tamar, “Go home to your father and live there as a widow until my son Shelah is grown up.” So Tamar went to live with her father.
