Thanks for the reference to the article. Great info.
Something else to think about:
Abraham was blessed that his posterity would be the "son of promise and covenant".
Galatians 4:22-31 Ishmael, "born according to the flesh": Isaac, "born according to the promise".
The Bible claims that Isaac was placed on the altar. I read somewhere (can't remember where, so this might not be true if we're relying on my memory) that Islamic tradition claims that Ishmael was placed on the altar. So, we have two half brothers fighting for 4,000years over the land of Israel that was promised to Abraham and his descendants.
Maybe there's nothing to it, but I find it "coincidental" that Isaac storms through right before all this upheaval in the Middle East occurs. I don't think it's so much about the land as much as it is a reminder of our covenants and judgment; if there's anything to it at all. (Sometimes I read to much into things).
