When the prophet Jeremiah prophesied that the sins of Israel
would bring about the destruction of the Holy Temple and
their exile to Babylonia, he also predicted the duration
of their punishment: So said G-d: After seventy years
in Babylonia, I shall remember you. I shall fulfill My good
word to you, to bring you back to this place.[1] But when the Second Temple was
destroyed 420 years after their return from Babylonia, and
the Jewish people were again driven from their land, no
pre-set limit was given for their exile.
The Talmud offers the following explanation: The
first exiles, whose sins were known (for we read how the
prophets rebuked them for idolatry, promiscuity and bloodshed),
the limit of their exile was also known; the latter exiles,
whose sin is not known, the limit of their exile is also
unknown.[2]
But on that very same page, the Talmud tells us that the
Second Temple was destroyed because of baseless hatred
between Jews. Why, then, are we told that their sin is unknown?
Said the Chassidic master, Rabbi Velvel of Zbaricz: Such
is the nature of baseless hatred. Each side
sees itself wholly in the right. It is the other who is
the sinner, the other whose inflexibility is the cause of
the dispute. So the strife and animosity go on without end,
for one cannot rectify a situation for which there is no
guilty party, and one cannot repent of a sin whose origin
remains an utter mystery...
