A divine judgment is set to transform the very centers of celebration into scenes of profound grief. Vineyards are traditionally spaces of happiness, closely tied to the joy of making and drinking wine. Yet, under this judgment, these fields will instead echo with wailing and sadness [ביאור שטיינזלץ]. The mourning in these locations stems directly from agricultural ruin. The vines will yield no grapes, resulting in a severe and deeply felt shortage of wine [מצודת דוד, רד״ק].
The root cause of this disaster is God's active presence moving through the nation to deliver a punishing strike [מצודת דוד, ביאור שטיינזלץ]. This divine movement is understood in different ways. It can be seen as a powerful metaphor for His anger and the harsh decrees that will sweep over the people [אבן עזרא]. Alternatively, the sheer severity of this event is underscored by comparing it directly to the Plague of the Firstborn. Just as God once passed through Egypt to strike it down, He will now pass directly through His own people to bring ruin and destruction [רד״ק].
