Once upon a time, there was a man, let’s call him B, who chanced upon a big fortune of 300 pieces of silver, which would make him very rich.
In those days, unlike now, there was no safe deposit box in banks for people to keep their treasure. In fact, there were no such things as banks. People either kept their treasure under ground or under their pillows. The very rich of course could have their own ‘fortune room’ guarded by their man servants.
So this guy B, who came into possession of 300 pieces of silver, did not have a safe place to keep this. The only place he could hide this treasure was to dig a hole inside his house compound and buried it. After burying the treasure, he suddenly thought of a ‘clever’ plan to make the treasure doubly-safe. Why not put a sign outside his house telling people that he did not possess this fortune?
So he put outside his house a sign saying that ” Inside this place, there is no 300 pieces of silver”. And another sign on the plot where he buried the treasure : “there is no 300 pieces of silver under this place”.
Very soon, the whole village knew that he had a treasure and on the same night , some unknown person came to his house and digged out the treasure.
When one made a declaration that he had done something, and then the next moment telling the whole world that what he just declared is not there, is it not same as B in this story?
