Gênesis 38

9 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 and that which he hath done is evil in the eyes of Jehovah, and He putteth him also to death.
