Human power often presents an illusion of control, especially when determining victory and defeat. The primary approach among commentators is that the events of the world serve as clear evidence of God's direct providence and its absolute superiority over human effort. If the world operated strictly according to the laws of nature, the king with the largest army and the warrior with the greatest physical strength would always emerge victorious. However, reality proves otherwise [רד״ק, מצודת דוד, ביאור שטיינזלץ].
There is a fundamental difference between relying on vast numbers and relying on personal ability, yet both ultimately fall short. A king, despite being considered the greatest among men and possessing top advisors, cannot truly depend on his strategies, decrees, or massive military camps [אבן עזרא]. A multitude of soldiers offers no real security [מצודת ציון]. Similarly, individual physical power and personal bravery offer no guarantee of survival for the lone warrior. Neither quantitative preparation nor qualitative strength can stand against the will of God [מלבי״ם].
Beyond simply being ineffective, human power can sometimes be the very cause of a person's downfall. When people place their trust in their immense strength or massive armies instead of trusting God, this excessive self-confidence leads them to carelessly walk into dangerous situations. In these cases, the feeling of power is the direct reason they fail [אלשיך].
History provides clear examples of this principle. Sennacherib, the king of Assyria, successfully conquered many lands as long as he served as an instrument of God. However, the moment he became arrogant about his vast army and credited his success to his own wisdom and might, he suffered a crushing defeat at the gates of Jerusalem. Likewise, the massive warrior Goliath fell at the hands of the young David, clearly illustrating how physical might cannot save anyone without God's will [רד״ק, מאירי].
