I have heard an anecdote told of Moses Montefiore explaining that his 'worth' was only what he gave to charity. This story is quoted in many places (ex. 1, 2, 3) to underscore the value of charity. I would like to know the source of the story. In one version I saw that the London Times published it along with other anecdotes to mark Montefiore's 100th birthday, but I have not been able to corroborate that.
