Fashionable, meaningless “social” chatter. A mix of stupidity and ignorance. Obviously beautifying a commandment costs money. In Jewish law this is defined as an obligation to add up to one-third more (Bava Kamma 9).
Does the Holy One, blessed be He, who grants reward for commandments, take a person’s financial situation into account? Obviously yes. So what? Does that mean one shouldn’t beautify the commandment?
And indeed, common sense is needed. Jewish law itself limits spending on a commandment (up to one-fifth of one’s assets) and on beautification (one-third). And each person knows his own situation and weighs what is reasonable to spend.
Is going to a movie justified when there are poor people? So why not spend the money on a more beautiful etrog?
Should I give up a specialist doctor because my poor colleague can’t afford one? And what about all kinds of food treats?
Bullshit
