2 Peter 2:4; 2 Peter 2:21

2 Peter 2:4

4 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;

2 Peter 2:21

21 For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.
