This psalm marks a dramatic transition from deep darkness and absolute despair to a profound light of hope, divine providence, and salvation. The opening words hold the key to understanding this emotional and historical shift, with the primary approach among commentators viewing them as a musical instruction. Some suggest this refers to a specific musical instrument known at the time [רש״י, רד״ק, מצודת ציון]. This instrument produced a sound that began low and soft, gradually increasing in volume, much like the slow breaking of the morning light [מאירי]. Alternatively, rather than an instrument, this may have been the title of a familiar melody or the opening lines of an ancient love poem, setting the tune to which the psalm was meant to be sung [אבן עזרא, ביאור שטיינזלץ].
Visually, the imagery evokes the morning star that illuminates the sky just before sunrise [רד״ק, מלבי״ם, מאירי]. A striking visual metaphor compares the first rays of morning light to the horns of a doe. Just as a doe's horns branch out and point in multiple directions, the dawn's light breaks and scatters, illuminating the sky everywhere, in sharp contrast to the light of the moon which rises straight like a stick [תורה תמימה]. Another perspective moves away from the animal imagery entirely, understanding the phrasing to represent strength and searching. In this light, the psalm is recited with great power at dawn, or it represents an intense search and demand for God [רש״י, רד״ק, אבן עזרא].
On a symbolic and historical level, commentators offer various perspectives on the central figure or era depicted. Some attribute the experiences directly to King David, who cried out to God from deep distress while facing mortal danger, either fleeing from Saul or nearly dying in battle [רד״ק, מאירי]. A widespread alternative views the text as a prophecy about Queen Esther and the Israelites, who faced total annihilation during the Babylonian exile [רש״י, רד״ק, אלשיך, מאירי]. This raises a natural question: why is the text introduced as a psalm of David if its subject is Esther? The connection lies in David's decision to spare the life of Shimei ben Gera, the ancestor of both Mordecai and Esther. Because David's mercy allowed Esther to eventually be born, the merit of saving the Israelites is credited to him [אלשיך].
Broadening this historical lens, the imagery serves as a metaphor for the entire nation of Israel enduring a long exile. The Israelites are compared to a beloved doe and the radiant beauty of the dawn, yet they find themselves trapped in darkness, seemingly abandoned and forgotten, crying out for redemption [רש״י, רד״ק, מאירי]. Ultimately, the opening concept encapsulates the sharp transition that defines the entire experience. It symbolizes the exact boundary line between darkness and light, between distress and salvation, and between absolute despair and an unwavering trust in God's providence and the miracle that is about to unfold [מלבי״ם].
