2And Judah saw there a daughter of a certain Canaanite, whose name was Shuah; and he took her, and went in unto her. 3And she conceived, and bare a son; and he called his name Er. 4And she conceived again, and bare a son; and she called his name Onan. 5And she yet again conceived, and bare a son; and called his name Shelah: and he was at Chezib, when she bare him.6And Judah took a wife for Er his firstborn, whose name was Tamar. 7And Er, Judah's firstborn, was wicked in the sight of the LORD; and the LORD slew him. 8And Judah said unto Onan, Go in unto thy brother's wife, and marry her, and raise up seed to thy brother.
