James 4:16

16As it is, you boast in your arrogance. aAll such boasting is evil.

2 Peter 2:18-19

18For, bspeaking loud boasts of folly, they entice by sensual passions of the flesh those who are barely cescaping from those who live in error. 19They promise them dfreedom, ebut they themselves are slaves
Greek bondservants
of corruption. For whatever overcomes a person, to that he is enslaved.

Jude 13

13 gwild waves of the sea, casting up the foam of htheir own shame; iwandering stars, jfor whom the gloom of utter darkness has been reserved forever.

Jude 16

16These are grumblers, malcontents, kfollowing their own sinful desires; lthey are loud-mouthed boasters, mshowing favoritism to gain advantage.

Revelation of John 18:7

7 nAs she glorified herself and lived in luxury,
so give her a like measure of torment and mourning,
since in her heart she says,
o‘I sit as a queen,
I am no widow,
and mourning I shall never see.’
