In moments of deep crisis and isolation, the sharp contrast between past joy and present suffering often sparks intense soul-searching. The imagery of night plays a dual role in this experience. It represents the quiet, literal night hours when a person's mind is clear and free to think [מצודת דוד], but it also serves as a metaphor for the dark, difficult period of exile [רש״י, מאירי]. During this darkness, memories of past joy surface. The poet recalls the songs of thanksgiving once sung to God for His kindness [ביאור שטיינזלץ]. This memory might be of the music played in the Temple in ancient times [רש״י, מצודת דוד, אבן עזרא], or the celebration that followed the redemption from the Egyptian exile [רד״ק]. Others suggest this memory refers to prayer [מאירי], the joyful chant of studying the Torah which often takes place at night [אלשיך], or even a prophetic vision of future salvation [מאירי]. There is a slight variation in how this memory unfolds, as the act of remembering might be happening during the night [מלבי״ם], or the memory itself is of playing music during the night hours [אבן עזרא].
This vivid memory triggers a deep internal dialogue. The poet reflects, struggles, and converses with himself [ביאור שטיינזלץ, מצודת דוד]. This inner conversation is a profound process of repentance. It is a moment where a person confronts their own nature, weighs their good deeds against their mistakes, and determines how to correct their behavior [אלשיך].
From this internal struggle emerges a deep investigation and inquiry [מצודת ציון, מלבי״ם], driven by the mind and human thought [רד״ק]. There are different perspectives on what exactly the mind is searching for during this intense reflection. One approach is that the mind seeks solutions and answers, trying to understand how the current hardship will eventually end [ביאור שטיינזלץ, מצודת דוד]. Another perspective suggests that the inquiry is directed outward toward God, questioning His ways and wondering if He has abandoned His people forever [רש״י, אבן עזרא]. A third view sees this as an inward journey, where the soul examines its own path, searching through its dark corners like a candle, in order to return to God completely [אלשיך].
