Which Old Testament passage says the most about resurrection and lays it out clearly?

Les explains that after looking at 1 Corinthians 15 and 1 and 2 Thessalonians concerning church age believers being caught up to meet the Lord, he goes back to Daniel chapter 12 to pick up the Old Testament believer. He says the Old Testament certainly alludes to resurrection, and they were believers of a resurrection, but not enough is said to build any real knowledge concerning it. Daniel chapter 12 probably says the most of anything, though Job made reference to his resurrection life and David expected to be resurrected. Daniel chapter 12 lays it out as clearly as any place. Starting at verse 1, Michael stands up, the great prince for Israel, and there is a time of trouble such as never was, a reference to the tribulation. At that time Israel shall be delivered, every one found written in the book, showing a delineation that unbelievers are not resurrected at the same time as the believer.
