Doug Rabin asked:
Why when it discusses Yosef's interaction with potiphar's daughter and his release of Zera, does it NOT discuss the averah of hotzah Zerah L'vatala
Douglas S. Rabin
The Kollel replies:
Maharsha (DH va'Yafutzu) says that when the Gemara here says Yosef lost 10 children because of this act, it means he was punished because of Hotza'as Zera l'Vatalah.
Best wishes,
