Contradiction with Proverbs 3:17
This verse says all of wisdom's ways are pleasant, contradicting Isaiah 14:8's suggestion of celebration at destruction.
Proverbs 3:17: Her ways [are] ways of pleasantness, and all her paths [are] peace.
Contradiction with Psalm 96:12
This verse depicts the trees rejoicing because of the Lord, not over a fallen oppressor as in Isaiah 14:8.
Psalm 96:12: Let the field be joyful, and all that [is] therein: then shall all the trees of the wood rejoice
Contradiction with Romans 12:19
This verse instructs believers to not seek vengeance, which contradicts the trees' rejoicing at the king's fall in Isaiah 14:8.
Romans 12:19: Dearly beloved, avenge not yourselves, but [rather] give place unto wrath: for it is written, Vengeance [is] mine; I will repay, saith the Lord.
