Contradiction with Proverbs 11:2
While Isaiah 9:9 mentions pride as a factor leading to downfall, Proverbs 11:2 contrasts by suggesting wisdom follows humility, opposing the reliance on pride seen in Isaiah.
Proverbs 11:2: [When] pride cometh, then cometh shame: but with the lowly [is] wisdom.
Contradiction with 1 Corinthians 10:12
Isaiah 9:9 implies self-assuredness in pride leading to downfall, whereas 1 Corinthians 10:12 warns against overconfidence, stating that one should take heed unless they fall.
1 Corinthians 10:12: Wherefore let him that thinketh he standeth take heed lest he fall.
Contradiction with James 4:6
Isaiah 9:9 highlights arrogance, but James 4:6 explicitly states that God resists the proud, contrasting with the attitude described in Isaiah.
James 4:6: But he giveth more grace. Wherefore he saith, God resisteth the proud, but giveth grace unto the humble.
