איכה, פרק ג׳, פסוק מ״ט

The aftermath of destruction brings a sorrow so deep that it manifests as an unending stream of tears. The profound sadness of the ruin causes tears to flow endlessly [ביאור שטיינזלץ, צאינה וראינה]. Some commentators take this imagery even further, suggesting a harsh physical reality: from such constant, unrelenting weeping, the eye itself seems to empty out and melt away [לחם דמעה].

Because the crying is so continuous, the eye finds no rest or quiet [ביאור שטיינזלץ, צאינה וראינה]. Alternatively, the damage from this endless weeping is so severe that the eye loses its very shape, no longer resembling a human eye at all [לחם דמעה, אלון בכות]. However, it is noted that this latter interpretation is unlikely from a strict linguistic standpoint [אבן עזרא]. This physical loss of form carries a deeper symbolic meaning. It reflects the spiritual blindness that descended upon the people during the destruction. Their vision was taken away, leaving them in darkness, and this spiritual sight will only be restored when God eventually brings the exiles back to Zion [אלון בכות].

The reason for this ceaseless weeping is rooted in the nature of the suffering itself. There is simply no break, pause, or relief from the ongoing troubles [רש״י, ביאור שטיינזלץ]. This intense pain and sorrow will only reach its conclusion when God looks down from heaven. While there is no explicit promise of redemption, there is a hint that the suffering has a limit. The agony will continue only until the Divine Spirit is awakened, a state that always precedes redemption. The act of God looking down is understood as an awakening and a pouring out of His spirit from above, which will ultimately bring the salvation needed to finally stop the tears [תורה תמימה].
