A dramatic call echoes across the nation, demanding immediate attention for a severe and unprecedented disaster that is about to unfold. The prophet directs this urgent message to two distinct groups, carefully tailoring his approach to each. First, he turns to the elders and leaders of the community. Because they have lived long lives and witnessed many historical events, they are uniquely qualified to testify whether anything like this impending doom has ever occurred [רד״ק, מלבי״ם, אבן עזרא]. After speaking to the leaders, the prophet calls upon the rest of the inhabitants of the land to lend their ears [מצודת ציון]. The ultimate goal is for the entire nation to witness this astonishing event so they can pass the story down to their children [מלבי״ם].
Addressing the elders first also serves a deep psychological purpose. The general public naturally looks to its leadership for guidance. When the masses see the elders reacting with dread to the prophetic warning, they too will be deeply moved and influenced [חומת אנך]. Furthermore, the prophet intentionally uses different forms of communication for each group. He directs a stronger, more significant command for attention toward the elders, while reserving a slightly lesser call for the general public, matching the weight of his words to the standing of his audience [מלבי״ם].
The core of the prophet's challenge is a historical question: has a tragedy of this magnitude ever happened in their lifetimes or during the days of their ancestors? [מצודת דוד, רד״ק]. He is referring to a devastating locust plague that will soon ravage the land [רש״י, מצודת דוד, ביאור שטיינזלץ]. However, this raises an obvious historical conflict. The famous locust plague in Egypt was declared to be an unprecedented event, with a promise that nothing like it would ever happen again.
The distinction lies in the nature of the destruction. During the time of Moses, the plague consisted of only one species of locust and occurred as a single, isolated event. In stark contrast, the disaster foretold here involves four distinct species of pests attacking in waves, one after the other, over four consecutive years to completely ruin the land. A complex and prolonged catastrophe of this kind had truly never been seen before, neither in their days nor in the days of their ancestors [רד״ק, אבן עזרא, חומת אנך].
