Contradiction with Exodus 20:12
While Job 31:8 implies a form of punishment for wrong actions, Exodus 20:12 promises prosperity through honoring one's parents without a specific consequence for wrongdoing.
Exodus 20:12: Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee.
Contradiction with Galatians 6:7
Job 31:8 describes a direct consequence of wrongdoing, whereas Galatians 6:7 sets a general principle of reaping what one sows, not mentioning punishment as direct as Job 31:8.
Galatians 6:7: Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.
Contradiction with Psalm 1:3
Job 31:8 suggests failure for wrongdoing, but Psalm 1:3 describes prosperity for the righteous, highlighting a positive outcome rather than punishment.
Psalm 1:3: And he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season; his leaf also shall not wither; and whatsoever he doeth shall prosper. [wither: Heb. fade]
Contradiction with Ezekiel 18:20
Job 31:8 implies children suffering for the parent's wrongdoing, whereas Ezekiel 18:20 states that the son will not bear the father's guilt, focusing on individual accountability.
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 Proverbs 11:18
This suggests that righteousness obtains a true reward, which indirectly contradicts Job 31:8's implication of losing reward due to wrongdoing without highlighting the righteousness aspect.
Proverbs 11:18: The wicked worketh a deceitful work: but to him that soweth righteousness [shall be] a sure reward.
