1 Samuel 17:7
And the shaft of his spear was like a weaver's beam, and his spear's head weighed six hundred shekels of iron — the comparison to a *weaver's beam* (*menor ha'oregim*, literally 'weavers' loom') renders Goliath's spear not as a weapon but as an instrument of trade, suggesting the Philistine capacity to transform every technology toward war. Six hundred shekels of iron—approximately fifteen pounds—is not merely heavy but grotesquely outsized, a weapon that requires exceptional strength to wield. The iron spear points to Philistine metallurgical superiority; iron is harder, holds a sharper edge, endures longer than bronze. Yet this technological advantage becomes, by narrative irony, irrelevant when confronted by faith and the power of the living God.
