2 Peter 2:4; 2 Peter 2:9; 2 Peter 2:17; 2 Peter 3:7

2 Peter 2:4

4 For if God did not spare angels when they sinned, but sent them to hell, putting them in chains of darkness to be held for judgment;

2 Peter 2:9

9 if this is so, then the Lord knows how to rescue the godly from trials and to hold the unrighteous for punishment on the day of judgment.

2 Peter 2:17

17 These people are springs without water and mists driven by a storm. Blackest darkness is reserved for them.

2 Peter 3:7

7 By the same word the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of the ungodly.
