5 And she yet again conceived, and bore a son; and called his name Shelah: and he was at Chezib, when she bore him.
6 And Judah took a wife for Er his first-born, whose name was Tamar.
7 And Er, Judah's first-born, was wicked in the sight of the LORD; and the LORD slew him.
8 And Judah said to Onan, Go in to thy brother's wife, and marry her, and raise up seed to thy brother.
9 And Onan knew that the seed would not be his: and it came to pass, when he went in to his brother's wife, that he frustrated the purpose, lest he should give seed to his brother.
10 And the thing which he did displeased the LORD: wherefore he slew him also.
11 Then said Judah to Tamar his daughter-in-law, Remain a widow at thy father's house, till Shelah my son shall be grown; (for he said, Lest perhaps he die also as his brethren did:) and Tamar went and dwelt in her father's house.
