Origin & History
Origins and dates here are approximate summaries. Many idioms have disputed or unknown origins, and not every date has been checked against a historical dictionary, so treat specific dates and stories as a starting point rather than a citation.
A plain literal image: unlike fruit or leaves, money cannot simply be picked from trees when more is needed.
