Job refers to himself by his "spirit" to emphasize his inner emotions. He speaks of not having any strength left as if he were something that has been used up. Alternate translation: "I am consumed" or "I have lost all of my strength" (See: [[rc://en/ta/man/translate/figs-synecdoche]] and [[rc://en/ta/man/translate/figs-metaphor]])
This phrase describes "the grave" as if it is a person who will receive Job as a guest. Alternate translation: "soon I will be dead and buried" (See: [[rc://en/ta/man/translate/figs-personification]])
