The vision of redemption presents a beautiful picture of cosmic harmony and reconciliation between God and His world. During the time of salvation, the curse that plagued nature throughout the days of destruction and exile will be lifted. The relationship between the Creator and creation will be completely renewed, marked by profound abundance and blessing.
A poetic chain of requests and responses links the different parts of creation. The thirsty earth longs for water, silently demanding it from the sky above. In turn, the heavens, eager to fulfill their potential and bestow goodness, turn to God to ask for permission to release their rain [מלבי״ם, מצודת דוד, ביאור שטיינזלץ].
The primary approach among commentators is that God's reaction is a direct answer to this plea, granting the wish of the heavens. However, this divine response is also understood as a constant, ongoing supply of abundance [אבן עזרא], or as the active pouring of goodness from the higher spiritual realms down into the physical world [רש״י].
On the day of salvation, God promises to accept the request of the skies. In stark contrast to the days of ruin when the heavens were blocked and sealed shut like iron, they will now be guided by direct divine care. God will direct the heavenly systems toward goodness, cancel any harsh decrees, and command the skies to empty their blessings upon the world [רד״ק, אבן עזרא, אברבנאל].
Following God's approval, the next phase of the chain unfolds. The heavens will answer the thirsty earth, fulfilling its deep longing by showering it with dew and favorable rains at their proper times. Through this process, a perfect synchronization is formed between the laws of nature and divine providence, allowing the entire world to experience complete blessing [מלבי״ם, מצודת דוד].
