Satan can only tempt those whom the Lord permits him to tempt (see Job 1-2). He is not allowed to tempt those who belong to a terrestrial order which includes all those who have been translated. Presumably, those of the city of Enoch were thus protected as were Elijah and Moses after they were translated. This is why Satan must be cast out during the Millenium, for the earth will be a terrestrial kingdom for those 1000 years, and Satan just doesn't belong to that order, not even as a devil.
