Question:Why does the Rambam poskin you get makkos (lashes) if your flour ferments on Pesach or if you buy chometz on Pesach because it is a prohibition done through an action but the mitzvah of don’t covet, even if it leads to convincing the other to buy the object he covets is still not considered a prohibition done through an action and hence does not receive makkos?
Background:
A. The real prohibition by chometz is owning it which is not an action (it is a state of being) and lashes are only a punishment for prohibitive actions. However since the ownership comes through an action of baking or buying then the prohibition is considered an action (Rambam first chapter of halachic Chometz u’Matza)
B. The Rambam (Hilchos gezeila vi’aveida 1:10) poskins If a person forces someone to sell him something even if he paid a lot of money for it he still transgresses the sin of “Don’t covet” but does not receive lashes because it is a sin which is not done through an action, rather it is an emotion manifested in an action of a forced sale.
Answer: The forced sale only reveals how much one covets the other person’s object so the sin really is only the emotion but by chometz the sale or baking is the actual means to be in a state of ownership of chometz therefore the sin is a direct result of the action and punishable with lashes.
