The birth of the Israelite nation did not unfold in lush, settled territories. Instead, their formation occurred in the extreme and unforgiving environment of the desert. Stripped of external influences and entirely dependent on heavenly grace, the people were chosen and molded by God through His close, miraculous providence. The primary approach among commentators is that God's discovery of the nation in this barren land highlights a deliberate choice. He found the Israelites to be faithful, willing to follow Him into a desolate wasteland, in stark contrast to other nations who refused to accept His kingship. Another perspective [רשב״ם, רא״ש, בכור שור ואחרים] suggests that this was a time of miraculous provision, where God supplied all their needs in the wilderness, such as the manna, the well, and the quail. Furthermore, the sheer hardship and suffering of the desert served a profound purpose. It humbled the hearts of the people, purifying them from the defilement of Egypt and preparing them to truly cling to God [כלי יקר, אור החיים]. This environment was a vast, empty, and dangerous wasteland devoid of water, echoing only with the howling of wild animals. Spiritually, it represented a zone of impurity and darkness that remained desolate until the giving of the Torah [רא״ש, אור החיים].
Within this terrifying emptiness, God provided a multi-dimensional layer of protection and structure, completely surrounding His people. Commentators identify three distinct circles of this embrace. Physically, God enveloped them with clouds of glory and protective angels. Organizationally, He structured their camp with four banners encircling the Tabernacle and the Tent of Meeting. Spiritually, He surrounded them at Mount Sinai, famously holding the mountain over them during the giving of the Torah [רש״י, ספורנו, שפתי חכמים]. Additionally, this encompassing care took the form of divine guidance that led the nation on winding, indirect paths through the desert to keep them safe from harm [רלב״ג, מלבי״ם].
Beyond physical safety, God opened their eyes with profound wisdom and understanding. By imparting the Torah and its moral pathways, He elevated them from a broken group of slaves into a complete, knowledgeable nation [העמק דבר, רש״ר הירש]. As a result of this intense closeness, God guarded the Israelites from every conceivable threat, whether from venomous snakes and scorpions, hostile nations, or spiritual decline. He protected them as fiercely and instinctively as a person guards their own eye. The primary approach among commentators is that this metaphor highlights the pupil, the delicate point of vision that requires the strictest defense against any foreign touch [רש״י, רבנו בחיי, אור החיים]. Conversely, other commentators [רשב״ם, רא״ש, בכור שור] suggest the imagery relates to the eyelid, which shields the eye and brings darkness during sleep. Regardless of the exact anatomical reference, the concept conveys the highest form of natural, uncompromising defense. Just as a person instinctively protects their vision, God guards His nation with love, for they serve as the spiritual eye through which He watches over and illuminates the earthly world [אלשיך].
