“1. We don’t here of such things today? You never heard of the Amityville Horror?”
No I didn’t
“2. There are stories of “tzaddikim” giving all their money to some needy person and leaving their own families high and dry”
They were expected to give everything they had whether spiritually or physically for the klal. Notice they didn’t keep any money for themselves either yet they all survived and thrived. Hashem provides for us day by day, just as He did with the mon, but it takes real bitachon to live that way.
But it works!
