Likkutei Sichos Vol. 33 – Shelach 2 – The Spies’ Mistake: Seeking Spiritual Perfection Instead of Divine Purpose – לקוטי שיחות חלק לג - שלח ב

From Likutei Sichos - Rabbi Chaim Wolosow by R Chaim Wolosow.

The Rebbe explores why the concept of a 'minyan' (quorum of ten) for sacred matters is derived from the spies, despite their sin. He explains that the spies were on a high spiritual level, desiring to remain in the desert's spiritual environment rather than engage in the physical tasks of settling the Land of Israel.
