תהלים, פרק צ״א, פסוק ו׳

A person who seeks shelter in God's shadow is guaranteed full protection from all dangers, whether they hide in the dark of night or strike openly in the middle of the day [ביאור שטיינזלץ, מלבי״ם]. Commentators offer two distinct ways to understand the exact nature of these threats, viewing them either as physical hazards or as supernatural forces.

From a natural perspective, these dangers refer to severe weather conditions and deadly illnesses. The darkness represents the literal night [מצודת ציון], and the pestilence is an epidemic that often grows worse during the cold night or under the heavy heat of the midday sun [אבן עזרא, רד״ק]. Another view frames these threats through the seasons, where the darkness symbolizes the intense cold of winter, and the midday represents the extreme heat of summer [מאירי]. In this context, the destruction refers to a tragic loss and annihilation of human life [ביאור שטיינזלץ, מצודת ציון, רד״ק, אבן עזרא, מאירי], or a toxic, deadly air [מלבי״ם]. The ruin brought by these physical forces is seen as a violent robbery that steals away human life [מצודת ציון, מלבי״ם, מאירי, רש״י, מצודת דוד].

In contrast to the physical reading, a supernatural approach understands these dangers as otherworldly entities. Rather than medical conditions or weather events, the pestilence and destruction are the actual names of demons and harmful spirits. The spirit known as pestilence operates under the cover of darkness, while the spirit named destruction steals souls and attacks during the noon hours [רש״י, מאירי, מצודת דוד]. Fitting with this supernatural view, the ruin they cause is not understood as a physical robbery of life, but rather as the direct, destructive work of a demon [אבן עזרא, מאירי].
