## You will come to your grave at a full age ##

"You will die at a ripe old age when it is your time"

## like a stack of grain sheaves that is carried up to the threshing floor ##

Eliphaz is using simile to make his point that Job will die when it is time for him to die. AT: "Just as grain is harvested at the appointed time, so shall you die when it is your appointed time." (See: [[rc://en/ta/man/translate/figs-simile]])

## See, we have examined this matter; it is like this; listen to it, and know it for yourself ##

"We" refers to Job's friends, including Eliphaz, who is speaking. AT: "Look, we have thought about this matter.  Listen to what I'm saying and know that it is true."  (See: [[rc://en/ta/man/translate/figs-inclusive]])
