Proverbs 23:31-33

New Catholic Bible

³¹ Do not note how red the wine is,
    how it sparkles in the cup,
    and how smoothly it goes down.
³² For in the end its bite is like that of a serpent
    or that of a poisonous viper.
³³ Then your eyes will behold strange sights,
    and your heart will utter distorted words.
