Genesis 38:8-11 ▼

8 Then 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.”

9 Now 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.

10 But what he did was displeasing in the sight of the LORD; so He took his life also.

11 Then Judah said to his daughter-in-law Tamar, “Remain a widow in your father’s house until my son Shelah grows up”; for he thought, “I am afraid that he too may die like his brothers.” So Tamar went and lived in her father’s house.
