A soft, comforting vision of Jerusalem's future redemption emerges through the intimate imagery of a caregiver tending to a newborn. After years of exile and suffering, the return to Zion represents a complete renewal, characterized by effortless abundance and an overwhelming sense of love and care.
God promises to actively direct a current of peace, redemption, and rest from enemies toward Jerusalem [שד״ל, מלבי״ם]. The primary approach among commentators is that God will bring a massive, powerful peace that flows continuously like river water. A nuanced view suggests that the peace itself defines the river, meaning this abundance will arrive gently and calmly, flowing smoothly without causing any harm [שד״ל].
Alongside this tranquil river, a second current will arrive, flowing with the speed and force of a flooded stream. This fast-moving water represents the sudden arrival of global wealth and greatness [מצודת ציון, שטיינזלץ]. The riches of the entire world will pour into Jerusalem rapidly and in massive quantities, yet just like the peaceful river, this powerful flow will not cause any destruction [רד״ק, מלבי״ם].
The imagery then shifts to that of a nursing infant. Just as a baby receives milk naturally and without physical strain, the Israelites will easily enjoy the wealth of the nations. After enduring deep sadness and mourning, they will receive this new prosperity without having to work or struggle for it [רד״ק, מצודת דוד].
The comforting picture continues with the depiction of caregivers who lovingly carry a baby on their side and playfully bounce him on their knees [רש״י, מצודת ציון]. This serves as a powerful metaphor for the gathering of the exiles. Since a small child cannot walk independently, he must be carried. In the same way, the nations of the world will physically carry the Israelites and bring them back from exile with great dignity [מלבי״ם, צאינה וראינה, אבן עזרא]. Ultimately, the Israelites will return to their homeland like a cherished little child, completely free from worry and pain, enveloped in pure joy, and honored by all the nations of the world [שטיינזלץ, רד״ק].
