Contradiction with Proverbs 10:4
Hard work, in contrast to the parables work needed for harvesting the good seeds, is praised here as labor brings profit, not necessarily the sowing of seeds.
Proverbs 10:4: He becometh poor that dealeth [with] a slack hand: but the hand of the diligent maketh rich.
Contradiction with Ecclesiastes 11:6
This verse encourages sowing seeds without knowing which will prosper, contrasting Matthew 13:3 where intentional sowing on good ground is emphasized.
Ecclesiastes 11:6: In the morning sow thy seed, and in the evening withhold not thine hand: for thou knowest not whether shall prosper, either this or that, or whether they both [shall be] alike good. [shall prosper: Heb. shall be right]
