Parshas Shlach: Rokeach – What Is The Connection Between The Mikoshesh Eitzim and Tzitzis?
The Rokeach answers with a Tanna D’bei Eliyahu that says, Hashem asked Moshe, “Why was the Mikoshsesh Michalel Shabbos?” Moshe didn’t know. Hashem said, “I will answer for you. Six days a week a person wears Tefilin on his hand and head. When he sees them, he refrains from doing aveiros. However, on Shabbos there is no Tefilin to remind him.” At that point Hashem told Moshe to go out and command the Bnei Yisroel to wear Tzitzis. The pasuk says, “You will see them and remember all the mitzvos of Hashem.”
