Dear moderator:
I'm not sure if the following Torah thought on this week's parsha belongs here, or in the baalei batim section. Feel free to put it wherever you see fit.
In בראשית לט:ו the Torah refers to אשת פוטיפר as לחם. Rashi says it is a לשון נקיה for wife.
The כלי יקר says something that I always had trouble with:
וקרא לאשתו בכינוי לחם, כי כמו שהלחם משביע לכל חי יותר מן כל דבר הזן, כך בעילות של היתר משביעים אותו אבר- לאפוקי בעילות של איסור אינן משביעים, כארז"ל אבר קטן משביעו רעב
Loosely translated: a wife is referred to through the euphemism of "bread", because just as bread satisfies more than any other food, so too, permitted intimacy (with one's wife) satisfies a person. In contrast, with prohibited forms of sexual relations, the rule is-as our sages say- the more you feed it the more it goes hungry.
I had major trouble with this כלי יקר on many fronts:
1) is bread really the most satisfying food? What percentage of the trillion dollar food industry is bread?
2) is sex with one's wife really more satisfying than with anyone else? What percentage of the trillion dollar sex industry is intimacy between a man and his own wife?
My bigger question is:
3) how can the כלי יקר say that the rule of our sages that "the more you feed it, the more you need it" only applies to prohibited relationships? One of the places that the gemara mentions this rule is with reference to דוד המלך, and it's clearly talking over there about intimacy with one wife! (I don't have a gemara in front of me, but I think it's Sanhedrin 107a- someone please correct me if I'm off)
The gemara there tells about how דוד knew that he was going to be tested in this area, so he slept with his wife in an attempt to minimize the נסיון. The gemara says that דוד forgot the rule that "the more you feed it, the more you need it", so he actually made it harder on himself. According to the kli yakar, it should have worked like "bread"- it was permitted intimacy!
I would really like to hear your thoughts on this. I have an idea based on what I've learned on this forum, but I haven't seen a מקור for it. Feel free to comment!
