The raw power of nature at sea is ultimately an expression of divine will. A sudden, violent storm that tosses a ship on the open ocean begins with a simple command from God. His absolute control over the elements requires no physical effort; it is triggered entirely by His speech. His spoken decree alone is enough to generate a massive storm [רד״ק, מצודת דוד, ביאור שטיינזלץ].
The primary approach among commentators is that this command is a direct activation of God's will, instantly awakening the fierce winds. However, an alternative perspective suggests that God directs His command to a specific spiritual force, the angel appointed over the sea. In this view, God gives the order, and this angelic guardian is the one who actively brings the fierce wind into existence [אלשיך].
Once the powerful wind is unleashed, whether directly by God or through His appointed angel, it crashes against the surface of the water. The force of the wind lifts the waters, creating massive waves across the sea where people are sailing [אבן עזרא, מצודת דוד, מלבי״ם]. These towering waves, driven by the stormy wind, are what cause the sailors' ship to violently rise and fall in the turbulent waters [רד״ק].
