If a man die, shall he live again? The question is clearly intended to be answered in the negative. It is not a dispassionate inquiry, but an expression of hopelessness. Let a man once die, and of course he cannot live again.
Were it otherwise, then, Job says, all the days of my appointed time will I wait; or, rather (as in the Revised Version), all the days of my warfare would I wait; i.e. I would patiently endure any sufferings in the larger hope that would then be open to me.
I would wait till my change (rather, my renewal) come. The exact nature of the 'renewal'' which Job seems here to expect is obscure. Perhaps he is pursuing the idea, broached in verse 13, of his being conveyed alive to Hades, and looks forward to a furthur renewed life after he is released from that "land of darkness."
