A common but flawed human assumption is that the vastness of the universe creates a blind spot for divine justice. The immense gap between a spiritual, exalted Creator and a lowly, physical world leads to the mistaken belief that human actions are completely hidden from God [תקות אנוש]. Because of this perceived disconnection, people might think they can act however they please under the cover of darkness, safely removed from any consequences [ביאור שטיינזלץ].
The primary approach among commentators is that this mindset raises a fundamental doubt about whether God is even aware of deeds committed in the shadows [רש״י]. This doubt is fueled by the vast distance between the earth and God's dwelling place far beyond the stars [מלבי״ם]. This sense of distance is made even stronger by the presence of a thick cloud [מצודת ציון] that serves as a hiding place [אבן עזרא]. While God's glory during moments of judgment is often described as resting within a thick cloud [מלבי״ם], here the cloud is viewed as an opaque screen. It acts as a solid physical barrier separating the observer from the observed [מצודת דוד, תקות אנוש].
This raises a twofold problem regarding divine oversight. First, there is the basic question of whether God can see through the darkness to judge the people on earth [רש״י, מלבי״ם]. However, a much deeper issue arises regarding the very nature of justice. Even if God could somehow look through this heavy barrier, true justice requires more than just a passing glance. It demands a direct, unfiltered look into a person's deepest thoughts and hidden intentions. A judge who only views the world through a thick, cloudy screen cannot possibly uncover the absolute truth required to judge the human heart [אלשיך].
