Deuteronomy 32:31-33

New Century Version

³¹ The rock of these people is not like our Rock;
    our enemies agree to that.
³² Their vine comes from Sodom,
    and their fields are like Gomorrah.
Their grapes are full of poison;
    their bunches of grapes are bitter.
³³ Their wine is like snake poison,
    like the deadly poison of cobras.
