ישעיהו, פרק ס״ה, פסוק י׳

The promise of redemption brings with it a profound physical renewal of the land, transforming ruined regions into places of abundance, security, and rest for those who are worthy. The flat, fertile district of the Sharon, stretching from the areas of Jaffa and Lod up to Mount Carmel [רש״י, שד״ל], will experience a remarkable restoration. It will become a secure pasture and dwelling place for grazing flocks [מצודת ציון, רד״ק]. Commentators offer different perspectives on the nature of this change. One view suggests that the land will experience such immense abundance that even the most premium soil, typically reserved for growing grain, will be available for grazing sheep [שד״ל]. Another perspective proposes that these grazing areas will specifically be established in regions less suited for grain [שטיינזלץ]. Regardless of the exact agricultural shift, the region will reclaim its former glory, completely shedding the desolation it suffered during the exile [מצודת דוד, רד״ק].

A similar transformation will occur in the Valley of Achor, an area situated either between Jericho and Ai [שד״ל] or in the surroundings of Jerusalem [אבן עזרא]. Historically, the valley's name reflected its troubled nature, known as a spoiled, muddy place with poor water quality, or carrying a derogatory reputation due to its past destruction [רש״י, מצודת ציון, מלבי״ם, שטיינזלץ]. In the future, however, this troubled valley will undergo a complete reversal, becoming a place of blessing and hope [רד״ק, שד״ל]. It will serve as a peaceful resting ground where cattle can lie down and graze in rich pastures. They will rest in absolute security, entirely free from the fear of enemies [מצודת ציון, רד״ק, מצודת דוד].

Yet, this promise of agricultural prosperity and national security is not guaranteed to everyone. It is strictly reserved for the righteous who actively sought God and remained devoted to Him throughout the exile, never abandoning Him for other gods [מצודת דוד, מלבי״ם, אבן עזרא]. These faithful individuals are the ones who will inherit the good land and live in it safely. This stands in sharp contrast to the sinners who turned away from God and are ultimately destined to be exiled from the land [רד״ק, שד״ל, שטיינזלץ].
