I sent a friend the borders of Israel as outlined in Numbers 34. (Actually, Israel's biblical claim to the Gaza Strip is weak to non-existent -- hmm...wouldn't PFAW and ADL have gone haywire if Robertson had said THAT!)
Israel's claim to the West Bank is solid -- and I have heard Muslims on TV say that they accept the Old Testament.
My friend responded that Jesus rendered most of the Old Testament void.
I said that was one interpretation.
Of course the other objection is that the modern-day Israel is a totally different entity from the Israel of Biblical times.
