As the “Black Death” plague decimated Europe, Christians accused the Jews of causing the plague by poisoning the wells in an effort to wipe out the Gentile population.
On the 23rd of Kislev 5109 (Nov. 15, 1348), Rudolph of Oron, bailiff of Lausanne, sent a letter to the mayor of Strasburg informing him that certain Jews of Lausanne had “confessed” under torture that they together with their coreligionists had poisoned all the wells in the Rhine valley. This resulted in the masses persecuting and killing tens of thousands of Jews throughout Europe.
Water and oil both represent wisdom.
Water represents the wisdom of life in this world, a wisdom that flows from the tallest mountain to the lowest valley, from the highest cloud to the deepest ocean floor. In all things, that wisdom breathes, telling us how to live, how to bring harmony into this world.
Oil represents a wisdom that is beyond this world. It is called the hidden wisdom because it is hidden by its very nature, so that it must be squeezed out of its source with great effort.
But if it is a wisdom that is beyond this world, why make the effort to reveal it? If we can live without it, why search for it?
We search for it to know why we should live in this world. To discover it is not just a world, but that it has purpose and meaning. That in its every cell, it contains G-d.
That is the wisdom that shines from the oil of Chanukah. In its light, we see the divine even in the darkness.
