There is a famous business concept called caveat emptor (buyer beware). In secular society, as long as a seller does not blatantly lie or actively conceal a defect, it is the full responsibility of the buyer to exercise due diligence and to inspect what is being purchased. Jewish law takes a totally different approach: It is presumed that no defects or problems exist in a product or property if they are not disclosed explicitly by the seller.
God is surely well-accustomed to all those vows from Lotto players, gamblers and risk-taking Wall Street investors about how much they’d give to charity if they hit paydirt. Even more than the Bucket List of things to do before we die, most people who aren’t wealthy have their own list of charities and worthy causes they would love to be able to bankroll before splurging on fast cars, big houses, exotic vacation and, for some, maybe settling their overdue day school tuition balance.
