38:7And Er, Judah's firstborn, was wicked in the sight of the LORD; and the LORD slew him.

38:8And Judah said unto Onan, Go in unto thy brother's wife, and marry her, and raise up seed to thy brother.

38:9And Onan knew that the seed should not be his; and it came to pass, when he went in unto his brother's wife, that he spilled it on the ground, lest that he should give seed to his brother.

38:10And the thing which he did displeased the LORD: wherefore he slew him also.

38:11Then said Judah to Tamar his daughter in law, Remain a widow at thy father's house, till Shelah my son be grown: for he said, Lest peradventure he die also, as his brethren did. And Tamar went and dwelt in her father's house.
