Genesis 38:8-10

Evangelical Heritage Version

⁸ Then Judah said to Onan, “Go to your brother’s wife. Perform your duty for her as the brother of her deceased husband and provide offspring^[a] for your brother.” 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.
