Furthermore, he notes that God endowed him with strength like bronze, indicating that he was equipped with a courage in combat that was not merely ordinary, but rather supernatural—something only God can impart to a person. Though David possessed inherent strength, his stature was not grand, as his sacred writings reveal, and this very comparison signifies a power that transcends human capability.
In the following verse, he proclaims that his protection and salvation came solely through God’s grace. He implies that without God’s miraculous preservation, he would have succumbed to many mortal threats. Thus, the defense provided by God stands in stark contrast to all weaponry and warfare strategies. In truth, his agility, physical strength, and military expertise would have been inadequate against King Saul and his formidable army, if not for the deliverance of God's salvation—God's protective hand that supports and empowers him. His subsequent words, "And your discipline will correct me in the end, and your discipline will teach me this," also reflect the same divine grace, which guided and nurtured him through all complex and bewildering situations, ensuring he would not stray or err. Here, "punishment" refers to the instruction derived from the law, and such understanding is only attainable through God's grace.
