London in the NT (which I don't think it is being studied by Ray or Jason ATM) it talks about Hades and Lake of Fire, as 2 distinct states of being. To me it seems Hades = Land of Darkness and Lake of Fire = Kaf HaKela.
Lake of Fire is called the second death. Hades is never called that. At some point, it says even Hades will be thrown into the Lake of Fire. If the correspondence is correct, then Land of Darkness is a temporary state which at some point, itself will be removed from the Universe into Kaf HaKela (supposing the correspondence is valid).

NT also talks about certain individuals that are so wicked that they are thrown directly into Lake of Fire, they are not given even the benefit of going through Hades (Land of Darkness?). It talks about 2 person that will be thrown into the Lake of Fire even while alive, without even going through the death experience.
