Quotes from the same author

Do not let the bread of the hungry mildew in your larder! Do not let moths eat the poor man's cloak. Do not store the shoes of the barefoot. Do not hoard the money of the needy. Things you possess in too great abundance belong to the poor and not to you. You are the thief who steals from God if you are able to help your neighbor and refuse to do it.

 Christine de Pizan
It is a deed of greater charity to give a bit of bread to the poor in the time of high prices and famine, than a whole loaf in the time of fertility and abundance.
