The roar of mighty waters serves as a powerful image of erupting force. Commentators debate whether this dramatic scene is a literal description of the natural world or a political metaphor regarding the nations of the earth.
The primary approach among many commentators views this natural display as a testament to the Creator. Rivers and seas, in their constant motion, raise their voices in an ongoing song of praise to God [אבן עזרא, ביאור שטיינזלץ]. The roaring currents serve as living proof that God controls the natural order and actively watches over the world. He established the boundaries of the oceans to make dry land and human settlement possible, a reality the rivers declare through both their flowing and their halting [מלבי״ם]. Even when the waters rise with fierce intensity—whipped into breaking waves by the winds that act as God's messengers [אבן עזרא]—they ultimately submit to Him as He dwells in His sanctuary [מלבי״ם באור המילות]. The very sound of these crashing waves captures the raw power of water washing over and crushing everything in its path [רד״ק, אבן עזרא, מצודת ציון, ביאור שטיינזלץ, מצודת דוד, מאירי]. This surging power is sometimes seen as originating from the lowest depths, from which the waters proudly swell upward [רש״י].
In contrast, other commentators interpret this watery force as a symbol of historical and national struggles. The roaring rivers represent the kingdoms of the world, sweeping across the earth like a massive flood. From this perspective, the imagery forms a cry of distress to God, complaining of how these foreign powers proudly raise their voices against Him [רש״י]. This metaphor also points toward the future, specifically the ultimate war of Gog and Magog, when kings will gather to fight against Jerusalem with a deafening noise resembling a raging river [רד״ק]. These empires use their might to threaten and terrify Israel, boastfully claiming they will flood the entire world like ocean waves [מצודת דוד, אלשיך]. In this symbolic light, the crushing nature of the breaking waves represents the deep oppression and brokenness that these foreign nations inflict upon the people of Israel throughout their exile [אלשיך].
