By covetousness they will exploit you with deceptive words; for a long time their judgment has not been idle, and their destruction does not slumber.

Doom of False Teachers

For if God did not spare the angels who sinned, but cast them down to hell and delivered them into chains of darkness, to be reserved for judgment;

then the Lord knows how to deliver the godly out of temptations and to reserve the unjust under punishment for the day of judgment,

But the heavens and the earth which are now preserved by the same word, are reserved for fire until the day of judgment and perdition of ungodly men.
