Job 14:2

Shadow. Pulvis et umbra sumus. (Horace iv. Ode 7.) "Come then, ye men, whom nature condemns to spend your days in darkness, ye who resemble the leaves, are of little strength, formed of mud, shadow-like,...of a day's duration, miserable mortals, men like dreams, attend to the immortals." (Aristophanes, Avib.) --- Most of these expressions occur in Job, Psalm ci. 12., Wisdom ii. 5., and Ecclesiastes ii. 23., &c.
