Contradiction with Matthew 19:30
This verse states the last shall be first, and the first last, implying a reversal of positions, which contrasts with the idea of a fair, agreed-upon wage in Matthew 20:4.
Matthew 19:30: But many [that are] first shall be last; and the last [shall be] first.
Contradiction with 2 Thessalonians 3:10
This verse states that if any would not work, neither should he eat, suggesting a merit-based system, which contradicts the equitable promise of work and pay regardless of hours worked in Matthew 20:4.
2 Thessalonians 3:10: For even when we were with you, this we commanded you, that if any would not work, neither should he eat.
Contradiction with Romans 4:4
This verse mentions that a reward is a debt for works, not grace, opposing the generosity implied in Matthew 20:4 where workers receive what is right, regardless of effort.
Romans 4:4: Now to him that worketh is the reward not reckoned of grace, but of debt.
Contradiction with Proverbs 14:23
This verse asserts that hard work brings a profit, while mere talk leads only to poverty, contrasting with the notion in Matthew 20:4 where payment is promised equally, regardless of varying lengths of labor.
Proverbs 14:23: In all labour there is profit: but the talk of the lips [tendeth] only to penury.
