The immense natural power reflected in creation, particularly in towering mountains, serves as tangible evidence of God's invisible strength. This vast display illustrates how divine power establishes and sustains the world, both through the physical stability of the earth and the life-giving forces of nature.
The primary approach among commentators is that these concepts describe the original creation and foundation of the world. God acts as the founder and builder of the earth [ביאור שטיינזלץ]. Mountains serve as massive, strong pillars upon which the earth rests [אבן עזרא]. Their very creation reflects the raw power and might with which the universe was formed [תורה תמימה]. Because God remains unseen, His immense strength is made visible to human eyes through the massive physical structures He formed, such as towering peaks built from thick layers of rock [אבן עזרא, ביאור שטיינזלץ].
In contrast to focusing on the physical stability of stone, another perspective views this as a description of nature's vitality and abundance. Through this lens, God prepares and brings down heavy rainfall to saturate the hard, dry mountains, causing vegetation to sprout and providing food for the world [רש״י, מצודת דוד]. This aligns with the traditional concept of the might of rain, highlighting the sheer force of falling water, which is deeply connected to the inner service of heartfelt prayer [תורה תמימה, רש״י]. Taking a more abstract approach, another interpretation links the establishment of these mountains to divine justice. It is God's perfect justice that truly founds the mountains, sustains the world, and triggers the falling of dew and rain that allows the peaks to flourish [מלבי״ם].
The imagery concludes with God girding Himself with might [ביאור שטיינזלץ]. Unlike flesh and blood, God does not need to draw or acquire strength from an external source in times of need. His power is a natural, permanent part of Him, worn constantly like a belt, and He can display it whenever He chooses [רד״ק]. Ultimately, these praises of nature's origins are not merely a reflection on the past. They point toward the future redemption, an event that will be so profoundly powerful it will be viewed as a complete resurrection or a brand-new creation of the world, echoing the original days of existence [מאירי].
