Genesis 38
2 Ref and Judah seeth there the daughter of a man, a Canaanite, whose name `is' Shuah, and taketh her, and goeth in unto her.
3 Ref And she conceiveth, and beareth a son, and he calleth his name Er;
4 Ref and she conceiveth again, and beareth a son, and calleth his name Onan;
5 Ref and she addeth again, and beareth a son, and calleth his name Shelah; and he was in Chezib in her bearing him.
6 Ref And Judah taketh a wife for Er, his first-born, and her name `is' Tamar;
7 Ref and Er, Judah's first-born, is evil in the eyes of Jehovah, and Jehovah doth put him to death.
8 Ref And Judah saith to Onan, `Go in unto the wife of thy brother, and marry her, and raise up seed to thy brother;'
9 Ref and Onan knoweth that the seed is not `reckoned' his; and it hath come to pass, if he hath gone in unto his brother's wife, that he hath destroyed `it' to the earth, so as not to give seed to his brother;
10 Ref and that which he hath done is evil in the eyes of Jehovah, and He putteth him also to death.
