G2217–ζόφος–zophos

For you have not come to a mountain that might be touched, and that burned with fire, and to blackness, darkness, tempest,

ζόφῳ zophō “to gloom”

For if God didn't spare angels when they sinned, but cast them down to Tartarus, and committed them to pits of darkness, to be reserved to judgment;

ζόφου zophou “of gloomy darkness”

These are wells without water, clouds driven by a storm; for whom the blackness of darkness has been reserved forever.

ζόφος zophos “gloom”

Angels who didn't keep their first domain, but deserted their own dwelling place, he has kept in everlasting bonds under darkness for the judgment of the great day.

ζόφον zophon “darkness”

wild waves of the sea, foaming out their own shame; wandering stars, for whom the blackness of darkness has been reserved forever.
