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.
This Shabbat is Shabbat Mevarchim ("the Shabbat that blesses" the new month): a special prayer is recited blessing the Rosh Chodesh ("Head of the Month") of upcoming month of Tevet, which falls on next Shabbat and the following Sunday.
Prior to the blessing, we announce the precise time of the molad, the "birth" of the new moon. See molad times.
It is a Chabad custom to recite the entire book of Psalms before morning prayers, and to conduct farbrengens (chassidic gatherings) in the course of the Shabbat.

“The human soul is a divine lamp.” (Proverbs 20:27)
The act of lighting the Chanukah menorah contains the entire purpose of every human being.
Because every human soul entered this world for one reason alone: To be a lamp. To bring light wherever there is darkness.
When you give people faith in themselves, in their future, in the sanctity of their own souls, you have not only brought them light—you have made them into human lamps.
You have given them their purpose.
