During the journey through the desolate wilderness, the Israelites experienced constant, miraculous care. While encamped, they found shelter from the intense heat within their physical tents, but the moment they set out on the road, a heavenly shield enveloped them to block the harsh dangers of the desert [העמק דבר, מלבי״ם]. The simple act of leaving their encampment to head toward a new destination triggered this divine cover [רש״י, ביאור שטיינזלץ].
On this particular journey, the arrangement of the divine presence shifted. Typically, a cloud traveled ahead to guide the way. However, because the Ark of the Covenant took the lead to map out the route, the cloud was free to hover directly above the people during the day, acting as a protective canopy [ספורנו]. Another perspective notes that as the Ark and its carriers began to move, the cloud intentionally lingered over the remaining tribes. This ensured the people were fully shielded until it was their turn to march [ביאור יש״ר].
Beyond acting as a physical shield, this presence provided miraculous illumination. Throughout forty years of wandering, the Israelites never required artificial light. The cloud functioned as a brilliant lantern that penetrated even the deepest, innermost rooms. This light provided special supervision and comfort for the most vulnerable members of the nation, such as the blind and the lame [צפנת פענח].
The primary approach among commentators is that the Israelites were actually wrapped in seven distinct Clouds of Glory. This formation included four clouds surrounding them on all sides, one above, one below their feet, and a final cloud leading the way. While most agree on the number seven, there are differing traditions. Some Talmudic sages suggest there were thirteen clouds, placing two in every direction, while others reduce the count to four or even just two [ריב״א, חזקוני]. The leading cloud had a very specific task to prepare the terrain. It leveled the landscape by lowering mountains and raising valleys, while simultaneously eliminating threats like snakes and scorpions [רש״י, מלבי״ם]. This vanguard cloud did not march directly in front of the people, but rather advanced ahead of the other six clouds that closely hugged the camp [ברכת אשר על התורה].
This all-encompassing protection raises an interesting question regarding the Commandment of the Sukkah, which serves as a physical reminder of these historical clouds. If there was indeed a cloud beneath the feet of the Israelites, why does a Sukkah only require a covering on top, rather than a floor covering as well? [מזרחי]. The answer lies in the nature of divine shelter. Any cloud originating from heaven, regardless of whether it physically rests below or beside a person, is fundamentally viewed as a force that hovers over them. Therefore, the roof of the Sukkah perfectly captures the essence of God's overarching, heavenly protection [גור אריה].
