Wife of Potiphar
Question
Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. Rashi explains that Egyptian women were black and ugly. Why then, was it such a nisayon for Yosef to resist the seduction of Potiphar's wife to sleep with him, to the point where his only recourse was to release his zerah by stuffing his fingers into the ground? Why was it such a nisayon to resist such an ugly woman? Do any of the meforshim address this? Thanks.
