The promise of future redemption and divine kindness unfolds through rich botanical imagery, painting a vivid picture of the restored relationship between God and Israel. This vision combines constant vitality, rapid blooming, and unshakable stability, serving as a complete reversal of the people's previously dry and desolate state. God promises to sustain the people like dew, which universally symbolizes unending divine abundance and kindness. Unlike rain, which can sometimes be withheld or even cause inconvenience to travelers, dew falls daily and benefits everyone [מצודת דוד, רד״ק, צאינה וראינה]. On a spiritual level, the descent of dew does not rely on water evaporating from the earth. This reflects how God’s kindness will awaken the people to repent from above, even if they lack the initial drive to do so themselves [אהבת יהונתן].
Nourished by this divine goodness, the people will blossom like a rose, a flower known for its rapid blooming and pleasant beauty [אבן עזרא, מצודת דוד, מצודת ציון]. Traditionally, the nation of Israel is compared to a rose among thorns, preserving its unique beauty even while surrounded by foreign nations in exile [רד״ק, אהבת יהונתן]. A distinct perspective links this imagery to the Rose of Jericho, a rootless desert plant that is carried aimlessly by the wind. The moment this dry plant absorbs the moisture of dew, it awakens to life and blooms magnificently. This serves as a precise metaphor for the Israelites wandering in exile, with God acting as the life-giving dew that enables them to flourish once again [מלבי״ם].
However, a rose carries a notable flaw: its roots are thin and weak, making it easily uprooted. To complete the blessing, the imagery shifts to the mighty forests of Lebanon [אבן עזרא, רד״ק, אהבת יהונתן]. The primary approach among commentators is that the people's roots will deepen and spread far and wide, much like the massive, branching roots of Lebanon's great trees. This combination ensures that Israel will enjoy the delicate beauty of a rose while remaining firmly and permanently planted in their land [מצודת ציון, רד״ק, ביאור שטיינזלץ, צאינה וראינה]. Alternatively, some suggest that it is the divine dew itself that will strike the roots and cause them to grow [רש״י]. In contrast, a different line of thought interprets this striking action as a past blow of drying and uprooting. According to this view, even though God previously struck the people's strong roots and uprooted them from their land like the trees of Lebanon, they will nevertheless manage to bloom anew like a resilient rose [מלבי״ם].
