G2217–ζόφος–zophos

For ye are not come to the mount that might be touched, and that burned with fire, nor to blackness, and to 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 to 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 who kept not their first state, but left their own habitation, he hath reserved in everlasting chains under darkness to 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”
