Contradiction with Ezekiel 18:20
While Deuteronomy 29:21 suggests collective punishment, Ezekiel 18:20 emphasizes individual responsibility for sin.
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 Jeremiah 31:29-30
Jeremiah refutes the idea of inherited punishment, emphasizing personal accountability contrary to the collective judgment indicated in Deuteronomy 29:21.
Jeremiah 31:29-30: In those days they shall say no more, The fathers have eaten a sour grape, and the children's teeth are set on edge.
Contradiction with 2 Kings 14:6
This verse contradicts Deuteronomy 29:21 by asserting that children should not be punished for the sins of their parents.
2 Kings 14:6: But the children of the murderers he slew not: according unto that which is written in the book of the law of Moses, wherein the LORD commanded, saying, The fathers shall not be put to death for the children, nor the children be put to death for the fathers; but every man shall be put to death for his own sin.
