Genesis 38:7-10

New International Version

⁷ But Er, Judah’s firstborn, was wicked in the Lord’s sight;^(A) so the Lord put him to death.^(B)

⁸ Then Judah said to Onan, “Sleep with your brother’s wife and fulfill your duty to her as a brother-in-law to raise up offspring for your brother.”^{(C) 9} But Onan knew that the child would not be his; so whenever he slept with his brother’s wife, he spilled his semen on the ground to keep from providing offspring for his brother. ¹⁰ What he did was wicked in the Lord’s sight; so the Lord put him to death also.^(D)
