Talmud zu Mischlej 1:31

A good deed takes root and yields fruit, as it says (Isaiah 3:10), “Say that the righteous is good, for he shall eat the fruit of his deeds.” A sin takes root but yields no fruit, as it says (Isaiah 3:11), “Woe to the evil wicked one, for what his hands have produced, will be done to him.” And some say: Sins do yield fruit, as it says (Proverbs 1:31), “They shall eat the fruit of their ways, and have their fill of their own counsels.”
