Contradiction with James 2:9
This verse condemns showing partiality, stating it is a sin and transgression of the law, which contrasts with Proverbs 28:21's implication that partiality is a more common and minor failing.
James 2:9: But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors.
Contradiction with Acts 10:34
States that God does not show favoritism, presenting a divine standard that contrasts with accepting human partiality mentioned in Proverbs 28:21.
Acts 10:34: Then Peter opened [his] mouth, and said, Of a truth I perceive that God is no respecter of persons:
Contradiction with Leviticus 19:15
Commands not to be partial in judgment, insisting on fair justice, which is contrary to the acceptance of partiality implied in Proverbs 28:21.
Leviticus 19:15: Ye shall do no unrighteousness in judgment: thou shalt not respect the person of the poor, nor honour the person of the mighty: [but] in righteousness shalt thou judge thy neighbour.
Contradiction with Deuteronomy 16:19
Prohibits twisting justice or showing partiality, which opposes the tolerance of partiality seen in Proverbs 28:21.
Deuteronomy 16:19: Thou shalt not wrest judgment; thou shalt not respect persons, neither take a gift: for a gift doth blind the eyes of the wise, and pervert the words of the righteous. [words: or, matters]
Paradox #1
The contradiction could be that favoritism and partiality are often viewed negatively as unfair and unjust, yet throughout history and other parts of the Bible, certain figures are seemingly favored by God or others for particular missions or roles. This creates a tension between the ideal of equality and the instances of favoritism depicted in religious texts.
