IIn Genesis 46:4, God speaks to Jacob to reassure him when he's about to go down to Egypt to see his long-lost son Joseph after about 22 years of thinking he was dead. Part of this reassurance includes a point-black statement by God, "I will bring you back."
Jacob dies in Egypt. His body gets brought back. Assuming the author and/or final editors of the text weren't complete idiots, they had to be aware that Jacob didn't go back to the land while he was still alive. So complex theories of different sources being conglomerated seem unlikely if we're to give even a modicum of charity to ancient Hebrew reporting.
What do we make of this, then? If we take the text at face value, then Jacob's bones being brough back to the promised land counts as Jacob being brought back. Does that mean Jacob's bones are Jacob? Can this fit with Paul's view in II Corinthians 5:1ff that we are naked until we get our heavenly tent? It's unclear if Paul is saying that there's an intermediate, disembodied state in which we are naked or if our current state is what's naked, and we will be clothed with the resurrection body. But either way it seems that our body is a tent.
Another thought worth considering is that God might have meant something more spiritual. God would bring Jacob back to the spiritual fulfillment of the promised land. But that seems to go against the natural reading of the text in light of what happens in Exodus, which is that God's statement would be fulfilled when Jacob's bones were brought back with the Israelites 400 years later. So even if there's some spiritualized meaning on top of the more obvious immediate one, it still seems as if there should be something to the more fundamental meaning.
So here is the question. Can we read any metaphysics of the human person off God's statement to Jacob? If not, why not? If so, what sort of metaphysics is at work, and how is it consistent with Paul's statements (because the metaphysics that seems most natural for Genesis 46:1 is a materialist one that seems flat-out inconsistent with Paul's statements).
