5. When Noah appeared in the world, he prepared spades and hoes, WHICH MEANS THAT HE PREPARED TOOLS TO TILL THE GROUND. THUS, IT IS WRITTEN OF HIM, "THIS ONE SHALL COMFORT US FROM OUR WORK AND THE TOIL OF OUR HANDS..." (BERESHEET 5:29). HE SHALL GIVE US TOOLS, SO THAT WE MAY BE FREED FROM PRODUCTION USING OUR BARE HANDS, FOR WHICH WE HAD BEEN DESTINED UNTIL NOW! Afterwards, however, "he drank of the wine, and was drunk; and he was uncovered within his tent" (Beresheet 9:21). And later, the people of the world sinned before the Holy One, blessed be He. And the powers of the earth disappeared again. THUS, ALL THE IMPROVEMENTS OF NOAH WERE LOST. And so it remained until Abraham appeared.
