There are many amazing stories of Rabbi Levi Yitzchak who is well-known as a zealous defender of and advocate for every Jewish soul. Quite a few of these stories relate to Yom Kippur.
This story is particularly relevant this year since Yom Kippur falls on Shabbos. It’s excerpted from an article on Aish.com:
One year, Rosh Hashana fell out on Shabbat, and Rabbi Levi Yitzhak went to the front of the synagogue to lead the congregation in prayer. Before beginning, he looked heavenward and said: “God, today is Shabbat. You taught us in Your holy Torah that Shabbat may only be broken in order to save a life. I demand that you keep the laws which You gave us. Since writing is a prohibited act on Shabbat, You have no right to record anybody in the Book of Death. You may only break Shabbat to record all of mankind in the Book of Life!”
So may it be! G’mar chasima tova!
