This rare noun denotes dust in its most broken-down, pulverized state. In Psalm 90, it appears in the sobering declaration that God causes humanity to return to dust, echoing the creation narrative of Genesis. The term emphasizes not merely dust as earth, but dust as the result of crushing or grinding down—the ultimate state of decomposition. The Spanish and German renderings as 'polvo' and 'Staub' capture the fine, powdery quality, while the French oddly translates as 'crushed,' highlighting the verbal action behind the noun.
