Proverbs 23:31-33

Complete Jewish Bible

³¹ Don’t gaze at the red wine
    as it gives its color to the cup.
It may glide down smoothly now;
³²     but in the end, it bites like a serpent —
    yes, it strikes like a poisonous snake.
³³ Your eyes will see peculiar things,
    your mind will utter nonsense.
