Contradiction with Proverbs 15:4
The crafty words in Proverbs 7:21 contrast with the wholesome, life-giving tongue described in Proverbs 15:4.

Contradiction with Philippians 4:8
Proverbs 7:21 reflects deceitful manipulation, in contrast to Philippians 4:8, which advises focusing on things that are true and praiseworthy.
Philippians 4:8: Finally, brethren, whatsoever things are true, whatsoever things [are] honest, whatsoever things [are] just, whatsoever things [are] pure, whatsoever things [are] lovely, whatsoever things [are] of good report; if [there be] any virtue, and if [there be] any praise, think on these things.

Paradox #1
The potential contradiction in Proverbs 7:21 could arise from the depiction of persuasive and seductive speech used to lead someone astray, which might seem to suggest that vulnerability to temptation is due to the fault of the seduced rather than emphasizing the responsibility of the seducer. This could be seen as conflicting with the broader Biblical principle of personal accountability and protecting others from harm.
