רוּחִ֣י חֻ֭בָּלָה יָמַ֥י נִזְעָ֗כוּ קְבָרִ֥ים לִֽי׃
My spirit is consumed, my days are extinct, The grave is ready for me.
Rashi
flicker Heb. נזעכו have sprung away, like (above 6:17) “they jump (נדעכו).”
Malbim
Is my spirit just on loan to be returned to its Maker at the body's demise, as Eliphaz maintains. No, my days are being ticked off, burying me one by one. There is nothing immortal in man. His whole life is lived here in this world, and every day that goes by is a day gone; irretrievable; buried.
