Theres a silver lining in every cloud. But did you know that silver is not part of the new Jerusalen and that Jerusalem means new salam so new jerusalem is actually new new salam ...
Jerusalem is a dual form noun, it means "possession of peace," or "foundation of peace." The dual form probably refers to the two mountains on which it was built, viz., Zion and Moriah; or, as some suppose, to the two parts of the city, the "upper" and the "lower city."
