A profound promise anticipates a future era of unprecedented spiritual awakening, where the world will be flooded with the knowledge of God and prophecy will return to illuminate reality. The primary approach among commentators is that this points to the End of Days and the Messianic era—a time of complete redemption when sin will cease, knowledge will multiply, and the world will return to its proper state [רש״י, רד״ק, מצודת דוד, אברבנאל, ביאור שטיינזלץ]. While a minority view suggests this refers to a past historical event during the reign of King Jehoshaphat, other scholars firmly reject this, emphasizing that it is a distinctly future destiny [אבן עזרא, אברבנאל]. This future era will be marked by a boundless granting of divine spirit. It is compared to water poured out all at once, covering all places equally in a massive display of abundance [מצודת ציון, מלבי״ם]. This spirit is not limited to prophecy; it encompasses a deep spiritual wealth of wisdom, understanding, awe of God, and a clear recognition of the Divine [רד״ק, חומת אנך, מלבי״ם, אברבנאל].
Regarding who will receive this spiritual outpouring, three central perspectives emerge. The broadest approach maintains that this abundance will rest upon all of humanity, with even the nations of the world coming to know and recognize that He is God [מצודת דוד, מצודת ציון, אברבנאל]. A second approach narrows the recipients to the people of Israel alone, particularly those dwelling in the Land of Israel—the appropriate place for the resting of the Divine Presence—or to those who have actively prepared themselves spiritually [רד״ק, אבן עזרא]. A third, metaphorical approach suggests that the spirit will rest upon anyone who has refined their character traits, cultivating a heart that is soft, sensitive, and receptive [רש״י].
Following long years of exile devoid of prophetic guidance, prophecy will make a glorious return. The spiritual abundance will be so widespread that even the youth will experience it, regardless of whether their ancestors were prophets [מצודת דוד, אברבנאל]. Nevertheless, this prophetic gift will not magically descend upon every individual; it will only be granted to those who are truly worthy and spiritually prepared [רד״ק, אברבנאל].
This divine revelation will manifest in three distinct levels: complete prophecy, which is the highest tier; a vision, which is a clear prophetic sight experienced while awake; and a dream, the lowest tier, which occurs during sleep and is sometimes mixed with mundane thoughts [מלבי״ם, חומת אנך]. The commentators offer two fascinating explanations for why the older generation will experience dreams while the younger generation will see visions. The first explanation points to historical proximity to the Messianic era. Children, born directly into this enlightened and spiritually prepared time, will merit complete prophecy. Young adults, born closer to this era, will experience visions. The elderly, however, having been born in earlier generations further removed from the time of redemption, will only experience dreams [מלבי״ם]. The second explanation focuses on the mental and physical states of the recipients. Older individuals, whose minds are burdened with a lifetime of memories and whose physical strength has waned, will receive their revelations during sleep, even though their minds are settled. In contrast, the younger generation, possessing clear minds and unburdened imaginations, will be capable of receiving the clearer, higher-level revelation of a vision while fully awake [אברבנאל, ביאור שטיינזלץ].
