Genesis 38 Intro: Birth of Er, Onan, and Shelah -- Er marrieth Tamar -- She deceiveth Judah.
1 And it came to pass at that time, that Judah went down from his brethren, and turned into a certain Adullamite, whose name was Hirah.
2 And Judah saw there a daughter of a certain Canaanite, whose name was Shuah; and he took her, and went in and lay with her.
3 And she conceived, and bare a son; and he called his name Er.
4 And she conceived again, and bare a son; and she called his name Onan.
5 And she yet again conceived, and bare a son; and called his name Shelah; and he was at Chezib, when she bare him.
6 And Judah took a wife for Er his firstborn, whose name was Tamar.
7 And Er, Judah's firstborn, was wicked in the sight of the Lord; and the Lord slew him.
8 And Judah said unto Onan, Go and marry thy brother's wife, and raise up seed unto thy brother.
9 And Onan knew that the seed should not be his; and it came to pass, when he married his brother's wife, that he would not lie with her, lest he should raise up seed unto his brother.
