True security brings a deep sense of protection that transforms how a person experiences both the present and the future. Vulnerability is replaced by absolute peace, carrying an individual through the challenges of this world and into the transition toward the next. This profound confidence stems from an awareness of the good reward granted by God [תקות אנוש], allowing a person to live calmly in the present [מצודת דוד]. Yet, this security contains a much deeper spiritual layer. Despite the temporary nature of physical life, true peace is achieved through the hope for a better, eternal existence [מלבי״ם]. It is even rooted in the faith and anticipation of a future resurrection of both body and soul [אלשיך].
This state of safety is illustrated through the imagery of digging, which commentators understand in two distinct ways. The primary approach among commentators views this as a metaphor for physical defense. It is as if a person has dug a deep, protective trench around themselves, much like a moat securing a city wall or a watchtower. Surrounded by this barrier, they can lie down to sleep in complete safety, knowing no one can approach or cause them harm.
Conversely, another perspective connects the act of digging to the very end of human life, viewing it as the preparation of a grave. According to this thought, the promise of safety extends beyond life itself; even when a person reaches their open grave, they will lie there in complete security [מלבי״ם, ביאור שטיינזלץ, תקות אנוש]. Rather than the fear and agony that typically accompany the departure from this world, resting in the earth will be completely free of sorrow or dread. A person can fully embrace this final rest, understanding that death is simply a quiet and peaceful lying down [אלשיך].
