Luke 21:4
All these people gave their gifts out of their wealth; but she out of her poverty put in all she had to live on — out of their wealth (ek tou perisseuontos, from their excess): the rich give from what remains after all needs are met. Out of her poverty she put in all she had to live on (holon ton bion, her entire livelihood): the widow gives what she cannot afford to give. The total giving is the measure of her greater gift.
