6. Judah got a wife named Tamar for his firstborn, Er.
7. But Er, Judah’s firstborn, greatly offended the Lord; so the Lord took his life.
8. Then Judah said to Onan, “Have intercourse with your brother’s wife, in fulfillment of your duty as brother-in-law, and thus preserve your brother’s line.”
9. Onan, however, knew that the offspring would not be his; so whenever he had intercourse with his brother’s wife, he wasted his seed on the ground, to avoid giving offspring to his brother.
10. What he did greatly offended the Lord, and the Lord took his life too.
