Commentators debate the exact means of the army's destruction—whether a direct angelic strike, a sudden pestilence, or a violent storm. However, they all agree on the central truth: this was a miraculous act of God. Scholars like Barnes and Ellicott suggest God likely used natural forces as His "angel" or messenger, while Calvin emphasizes a direct, supernatural act. The key lesson is that God's power is not limited, and He can work through visible or invisible means to fulfill His promises.
