This verse states that a son will not bear the iniquity of the father, yet Proverbs 10:7 suggests a long-lasting memory of the wicked which may affect descendants.
Ezekiel 18:20: The soul that sinneth, it shall die. The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him.
Contradiction with Ecclesiastes 9:5
This verse claims that the dead know nothing and are forgotten, in contrast to Proverbs 10:7 which indicates that the memory of the wicked will rot, implying remembrance.
Ecclesiastes 9:5: For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten.
Contradiction with Isaiah 43:25

Contradiction with Psalm 103:12
