2. There Judah met the daughter of a Canaanite man whose name was Shua. He married her and slept with her.
3. She became pregnant and gave birth to a son named Er.
4. She became pregnant again and gave birth to another son, whom she named Onan.
5. Then she became pregnant again and gave birth to another son, whom she named Shelah. He was born at Kezib.
6. Judah chose a wife for his firstborn son Er. Her name was Tamar.
7. Er angered the Lord. So the Lord took away his life.
8. Then Judah said to Onan, “Go sleep with your brother’s widow. Do your duty for her as a brother-in-law, and produce a descendant for your brother.”
9. But Onan knew that the descendant wouldn’t belong to him, so whenever he slept with his brother’s widow, he wasted his semen on the ground to avoid giving his brother a descendant.
