I had 2 related thoughts/observations to share. I find it interesting that Sheol, the Pit is frequently mentioned as something from which people want to be protected and which seems to approximate modern concept of hell, but that there is no heaven or paradise alluded to. It seems that the reward is a painufree earthly existence, which is guaranteed if you fear and praise God. I wonder where the concept of heaven originates. On a related note, in Psalm 106.28, the people are reprimanded for making sacrifices to the dead as part of a Baal worship ritual. I wonder if the fear of Sheol/death is meant to repudiate veneration of the dead and, hence, Baal worship.
Anyway, just something to kick around.
