ישעיהו, פרק ט׳, פסוק א׳

A sudden, dramatic shift from deep despair to unexpected salvation is powerfully captured through the imagery of heavy gloom breaking into brilliant dawn. The primary approach among commentators is that this prophecy focuses on the residents of Jerusalem, specifically the tribes of Judah and Benjamin, during the terrifying siege by Sennacherib, King of Assyria. The crushing anxiety of the people is compared to wandering in complete darkness, stumbling through the streets like blind men overcome with sorrow [אבן עזרא]. This heavy gloom, likened to the shadow of death or the darkness of the grave [מצודת ציון, ביאור שטיינזלץ], is abruptly shattered by a great light. This light represents the miraculous downfall of the Assyrian army and the sudden rescue of Jerusalem. The promise of this salvation was likely delivered earlier, during the reign of King Jotham, coinciding with the birth of Hezekiah, to guarantee the great rescue that would occur during his rule [שד״ל].

Alongside this physical rescue, the imagery holds a deep spiritual dimension. The darkness reflects the era of rampant idol worship during the reign of King Ahaz. This spiritual gloom was eventually replaced by the great light of a return to the Torah and faith under his son, Hezekiah [אברבנאל]. This revival stood in sharp contrast to the tribe of Ephraim, which remained completely submerged in darkness during that period. The experience of this darkness can be divided into two distinct situations. First, there were the residents of Judah who actively hid their faces from the divine light that was already present, yet they were destined to uncover it. Second, there were the distant exiles who lived in an absolute lack of light, but they too would return to find shelter in God's salvation [מלבי״ם]. When this divine light finally breaks through, it is not a harsh, direct glare. Instead, it is a softer illumination, much like reflected moonlight or the gentle glow just before sunrise when the sun's rays catch the rising mist from the earth [מלבי״ם].

In stark contrast to these explanations, another perspective entirely removes the context from the era of Hezekiah and places it during the Exodus from Egypt. According to this line of thought, those walking in darkness were the Israelites moving through Egyptian homes during the Plague of Darkness, for whom a miraculous, great light suddenly appeared. At the same time, those dwelling in the deepest shadows represent the Israelites living in the land of Goshen, where a constant, unbroken light shined for them without any darkness at all [חומת אנך].
