The Philistines haven't gone anywhere, they have not disappeared from history, they still live in the same place where their ancestors lived, and have intermingled even further since the Islamic conquest of the region in the 7th century AD. There are even greater details that I could cite from the text of Moses in Genesis and of Asaph in Psalm 83, but this should serve to make the point I have made sufficiently.
Now, to be clear, I have assumed Dr. Thomas Ice actually wrote and is therefore responsible for the whole of "Consistent Biblical Futurism (Part 10)" and the errors I have cited here; that Part 10 wasn't just some cut and pasted work done by an intern within his ministry. Nevertheless, the error is a significant one in my opinion, and should preclude Dr, Ice's from publishing and widely distributing a personal attack and Scripturally-incorrect article like his "Consistent Biblical Futurism (Part 10)" has turned out to be. This is something I ordinarily would never have expected to see published on the Pre-Trib Research Center's website, and that is truly just a crying shame.
