[the witch king]

'Who is the lord of darkness?' Then behind locked doors Sauron spoke to the king, and he lied, saying: 'it is he whose name is not now spoken; for the Valar have deceived you concerning him, putting forward the name of Eru, a phantom devised in folly of their hearts, seeking to enchain Men in servitude to themselves. For they are the oracle of this Eru, which speaks only what they will. But he that is their master shall yet prevail, and he will deliver you from this phantom; and his name is Melkor, Lord of all, Giver of Freedom, and heshall make you stronger than they.'

Then Ar-pharazon the King turned back to the worship of the dark........

Just love the wat Sauron talks about Melkor, and its kind of after theys words are spoken that Numenor choose's to rebel.
