יואל, פרק ב׳, פסוק כ״ד

A vision of immense agricultural abundance unfolds, portraying a reality where the earth's yield transcends the ordinary laws of nature. This extraordinary plenty is a direct result of God's blessing [מלבי״ם]. The promise of prosperity begins with the harvest of the fields. The threshing floors, the central gathering places for the crops, are guaranteed to be completely filled with an abundance of grain [מצודת ציון, ביאור שטיינזלץ].

Following the solid harvest, this divine blessing extends to the liquid crops. Wine and oil are destined to flow in massive quantities into the collection vats, the deep pits positioned just below the presses to catch the extracted liquids [רש״י, מצודת ציון]. The exact nature of this heavy flow is understood in a few different ways. One approach focuses on the loud noise created by the liquids. Because the volume of wine and oil will be so massive, a powerful roaring sound will be heard as the heavy streams pour forcefully into the vats [רש״י, מצודת דוד, מצודת ציון].

A second perspective highlights the sheer volume, explaining that the vats will become so incredibly full that the wine and oil will overflow their brims [רד״ק, ביאור שטיינזלץ]. This idea draws upon early Rabbinic terminology regarding ritual baths, where waters are brought together until they connect, merge, and rise above their usual levels [רד״ק]. Finally, a third view offers a more straightforward understanding, noting that the storage vats will simply be filled to capacity with an enormous supply of drink [מלבי״ם].
