I agree. But I would like to challenge you to provide just one example from a pre-captivity text which teaches the eschatological notions in question.
Well, first of all, your "proofs" for your stand on this topic are pretty vague and without any more validity than your own opinion.
I gave a few actually. The promises to Abraham, to David. I also gave proof of Christ's own words concerning God being the God of Abraham, Isaac and Jacob. There is the utterance of Job concerning his own awaking from death, along with the prophecies of David as made mention by the Apostle's sermons in Acts. All these examples come from pre-captivity OT scriptures.
Here's a good starting point.
