I think it is the rest (comfort) spoken (prophesied) here.
Gen 5:28 And Lamech lived an hundred eighty and two years, and begat a son:
29 And he called his name Noah, saying, This same shall comfort us concerning our work and toil of our hands, because of the ground which the LORD hath cursed. {Noah: Gr. Noe: that is Rest, or, Comfort }
Until Noah, the ground was cursed, with thorns and thistles. This was so prolific that Adam had sweat on his brow All the days of his life just to eat from it. It became so difficult just to eat from the ground that there was no rest (sabbath) from it.
Not only was Noah able to eat from the ground easily, it produced in abundance thus the story of him drinking wine to drunkeness. He had plenty to let it ferment. God furthermore gave to Noah additional food, to further ease of food sources. Which sources also helped in the maintenance of the ground. Both in plowing, treading out grain, keeping down unwanted growth. Just my thoughts.
But it had to do with rest from the cursed ground until that time.
