תהלים, פרק קכ״ו, פסוק ד׳

From the depths of exile, the Israelites offer a desperate, poetic prayer for a dramatic and life-giving change. They ask God to return them to their home, seeking a swift transition from ruin to complete redemption [אבן עזרא, רד״ק, מצודת דוד]. To express this, they use the powerful image of mighty, rushing streams of water suddenly flooding a hot, parched desert [מצודת ציון, אבן עזרא, מאירי]. The primary approach among commentators is to view the exile as a dry wasteland and salvation as living water. Exhausted and battered by their troubles, the people thirst for God's rescue, praying that His redemption will revive them just as water quenches thirsty earth [רד״ק, מאירי].

This imagery of rushing water in a dry land highlights several different hopes for how redemption will unfold. One perspective focuses on suddenness. Just as dry riverbeds in the desert can instantly fill with flash floods from distant rains, without any warning signs of clouds or wind, redemption can appear by surprise even when reality seems entirely hopeless [ביאור שטיינזלץ]. Another view sees this as a plea for a swift and absolute rescue. Rather than a slow, gradual process, the prayer asks for salvation to happen all at once, much like a sudden flood that completely fills an empty channel from end to end in a single moment [אלשיך].

Building on this theme, the sudden rush of water also represents a plea for salvation to arrive earlier than expected. If rescue comes exactly when planned, the resulting joy is normal and predictable. However, an early and unexpected redemption is like a person who plants seeds in a dry wasteland and completely gives up hope. When water suddenly arrives to make the crops grow, that deep despair transforms into an overwhelming, unprecedented joy [מלבי״ם]. This life-giving water ensures that those who planted with worry and tears, fearing their crops would fail in the barren land, can suddenly harvest with happiness [רש״י]. The profound connection between water and redemption is so powerful that the sages concluded the day rain falls is just as great and significant as the day the exiles are finally gathered [תורה תמימה].
