If a man die, shall he live again? all the days of my appointed time will I wait, till my change come.
Shall he live? - The answer implied is, There is a hope that he shall, though not in the present order of life, as is shown by the words following. Job had denied (Job 14:10-12) that man shall live again in this present world. But hoping for a "set time" when God, shall remember and raise him out of the 'hiding'-place of the grave (Job 14:13), he declares himself willing to 'wait all the days of his appointed time' of continuance in the grave, as well as now in this present life of trial, however long and hard that may be.
Appointed time - literally, warfare, hard service; implying the hardship of being shut out from the realms of life, light, and God for the time he shall be in the grave (Job 7:1).
Change - my release, as a soldier at his post released from duty by the relieving guard (note, Job 10:17), (Unbreit and Gesenius): but elsewhere Gesenius explains it renovation, as of plants in spring (Job 14:7); but this does not accord so well with the metaphor in "appointed time" or 'warfare.'
