Genesis 38:6-10

Judah and Tamar

⁶Now Judah took a wife for Er his firstborn, and her name was Tamar. ⁷But Er, Judah’s firstborn, was evil in the sight of the Lord, so the Lord took his life. ⁸Then Judah said to Onan, “Have relations with your brother’s wife and perform your duty as a brother-in-law to her, and raise up a child for your brother.” ⁹Now Onan knew that the child would not be his; so when he had relations with his brother’s wife, he wasted his seed on the ground so that he would not give a child to his brother. ¹⁰But what he did was displeasing in the sight of the Lord; so He took his life also.
