Genesis 38:9-11

Evangelical Heritage Version

⁹ Onan knew that the offspring would not be his, so whenever he went to his brother’s wife, he wasted his semen on the ground, so that he would not provide offspring for his brother. ¹⁰ But the thing that he did was evil in the sight of the Lord, so the Lord killed him also.

¹¹ Then Judah said to Tamar, his daughter-in-law, “Remain a widow in your father’s house until my son Shelah is grown up.” Actually he had said to himself, “I do not want him to die like his brothers.” So Tamar went and lived in her father’s house.
