Contradiction with Proverbs 3:27
This verse advises us not to withhold good from those to whom it is due, which may contradict the implied notion of deservedness in being rewarded for labor specifically outlined in 1 Timothy 5:18.
Proverbs 3:27: Withhold not good from them to whom it is due, when it is in the power of thine hand to do [it]. [them...: Heb. the owners thereof]
Contradiction with Ecclesiastes 9:11
This verse suggests that the race is not always to the swift and doesn’t always reward labor directly, implying that rewards are not guaranteed for work, contradicting the notion in 1 Timothy 5:18.
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.
