Man that is born of a woman is of few days, and full of trouble. He cometh forth like a flower, and is cut down: he fleeth also as a shadow, and continueth not.
Genesis 3:17-19
And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life... In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
Job's meditation on human brevity is a poetic elaboration of the Genesis 3 covenant curse. The divine sentence over Adam established the constitutional parameters of post-fall human existence: labor, sorrow, and return to dust. Job's 'few days, full of trouble' is the experiential reality of the Adamic curse — the suffering and transience that Genesis 3 encoded into the human condition as the covenant consequence of the original transgression. Job's lament is theologically grounded in the foundational statute, not mere personal misfortune.
