6 And Judah took a wife for Er his firstborn, and her name was Tamar. 7 But Er, Judah’s firstborn, swas wicked in the sight of the Lord, and the Lord put him to death. 8 Then Judah said to Onan, “Go in to tyour brother’s wife and uperform the duty of a brother-in-law to her, and raise up offspring for your brother.” 9 But Onan knew that the offspring would not be his. So whenever he went in to his brother’s wife he would waste the semen on the ground, so as not to give offspring to his brother. 10 And what he did was wicked in the sight of the Lord, and he put him to death also.
