Why is this Shabbos called “Shabbos Hagadol”?
The Chidushei Harim zy”a answers that the word “Shabbos” can mean to remove, as in Vayikroh 26:6: “V’hishbeisi chaya ra’ah min ha’aretz.” (And I will remove the wild animals from the land.) This Shabbos annuls and removes a person’s pride and haughtiness. It uplifts a person until he feels how lowly he is in relation to Hashem. Thus, it is “the great Shabbos”, as it teaches us that Hashem is the only power and man is nothing in comparison to Him.
