Contradiction with John 7:4
While Acts 19:30 shows Paul's willingness to face danger by entering the theater, John 7:4 suggests that one should not seek public attention in a potentially threatening situation.
John 7:4: For [there is] no man [that] doeth any thing in secret, and he himself seeketh to be known openly. If thou do these things, shew thyself to the world.
Contradiction with Proverbs 22:3
Acts 19:30 presents Paul intending to confront the crowd, whereas Proverbs 22:3 advises prudence and avoidance of danger.
Proverbs 22:3: A prudent [man] foreseeth the evil, and hideth himself: but the simple pass on, and are punished.
Contradiction with Matthew 10:23
In Acts 19:30, Paul wants to go into the theater, but Matthew 10:23 advises fleeing persecution rather than facing it.

Contradiction with Ecclesiastes 3:1
Acts 19:30 shows an urgency to act, whereas Ecclesiastes 3:1 implies there is a correct time and not all moments are fit for immediate action.
Ecclesiastes 3:1: To every [thing there is] a season, and a time to every purpose under the heaven:
Contradiction with Proverbs 14:16
Paul's desire to enter the theater in Acts 19:30 is contradicted by the wisdom in Proverbs 14:16 that suggests a wise man fears and avoids evil.
Proverbs 14:16: A wise [man] feareth, and departeth from evil: but the fool rageth, and is confident.
Contradiction with Matthew 7:6
Acts 19:30's intention to confront the crowd can be seen as contradicting Matthew 7:6, which advises against giving what is sacred to those who may not value it.
Matthew 7:6: Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.
