מלכים ב, פרק י״ח, פסוק כ״א

Facing a severe military threat, Judah finds its independent forces helpless, prompting harsh mockery from the Assyrian spokesman. He sharply criticizes their decision to place their trust in a foreign power [מדוד ועד לחורבן, מצודת דוד]. The alliance with Egypt is portrayed not merely as useless, but as an active danger. To illustrate this, a vivid comparison is drawn of a frail person seeking support from a walking stick. However, the stick in question is actually a crushed and broken reed [מצודת ציון, ביאור שטיינזלץ]. Specifically, its top portion is already fractured [רד״ק, מצודת דוד].

When a person attempts to lean on this damaged reed, they quickly discover it is far too weak to bear their body weight [ביאור שטיינזלץ]. The situation then turns from disappointing to dangerous. As the reed snaps under the pressure, its sharp, splintered edges pierce directly into the flesh of the person's palm, leaving a painful wound [רש״י, רד״ק, מצודת דוד, מצודת ציון, ביאור שטיינזלץ].

The commentators agree that this imagery perfectly captures the reality of relying on Pharaoh, the King of Egypt. Egypt lacks the strength to serve as a stable foundation and proves to be an unreliable ally incapable of keeping its promises [ביאור שטיינזלץ]. Consequently, anyone who places their faith in Egyptian support will find that the very help they hoped for ultimately transforms into direct harm and disaster [מצודת דוד, ביאור שטיינזלץ].
