Contradiction with Proverbs 10:4
This verse suggests that the diligent hand makes rich, aligning with the idea of working hard to avoid poverty, which is not directly contradictory to Proverbs 13:18, but rather supportive.
Proverbs 10:4: He becometh poor that dealeth [with] a slack hand: but the hand of the diligent maketh rich.
Contradiction with Ecclesiastes 9:11
This verse indicates that success is not always due to wisdom or diligence, but can be due to time and chance, which contradicts the deterministic view of poverty and shame as direct consequences of actions in Proverbs 13:18.
Ecclesiastes 9:11: I returned, and saw under the sun, that the race [is] not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to men of understanding, nor yet favour to men of skill; but time and chance happeneth to them all.
