G2217–ζόφος–zophos

For ye are not come unto the mount that might be touched, and that burned with fire, nor unto blackness, and darkness, and tempest,

ζόφῳ zophō “to gloom”

For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment;

ζόφου zophou “of gloomy darkness”

These are wells without water, clouds that are carried with a tempest; to whom the mist of darkness is reserved for ever.

ζόφος zophos “gloom”

And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.

ζόφον zophon “darkness”

Raging waves of the sea, foaming out their own shame; wandering stars, to whom is reserved the blackness of darkness for ever.

ζόφος zophos “gloom”
