The Mekhilta offers a vivid parable to distinguish God's warrior nature from every human warrior. Consider, it says, a warrior in a province who is fully equipped with every weapon of war — sword, shield, bow, spear, armor — the finest military hardware available. He looks magnificent. But he lacks the things that actually win battles: power, strength, stratagem, and the wisdom of war.
This is the tragedy of the human warrior. Equipment is not the same as ability. A man can wear the armor without possessing the courage. He can carry the sword without knowing when to strike. He can own every weapon and still lose the fight because his heart is weak, his mind is slow, or his strategy is foolish.
Not so the Holy One Blessed be He. God possesses all of these qualities — not partially, not occasionally, but absolutely and permanently. As the proof texts demonstrate: "For unto the Lord is the war, and He will deliver you into our hands" (1 Samuel 17:47) — these were the words spoken by David to Goliath, declaring that the battle belongs entirely to God.
And from David's own psalm: "Blessed is the Lord, my Rock, who trains my hands for battle, my fingers for war" (Psalms 144:1). God does not merely fight — He trains others to fight. He is both the supreme warrior and the supreme instructor. The Mekhilta's point is that no analogy from human warfare fully captures what God is. Every human warrior is incomplete. God alone combines perfect equipment with perfect power, perfect strength, and perfect wisdom.
