What is the old testament conception of resurrection and afterlife?

[fhightower]

Especially when reading books like Job, it raises the question: what did OT authors know about the afterlife? In Job 14:13-17, Job seems to affirm an afterlife ("sheol"), but then wishes for a resurrection and a chance to stand before God after death. In chapter 27, however, Job seems convinced that there is an afterlife in which the wicked will be punished. How much did Job and other OT characters know about the afterlife, resurrection, and judgement?
