In the end it bites like a snake and stings like a viper.
In context
30Those who linger over wine, who go looking for a blended cup. 31Do not look at wine when it is red, when it sparkles in the cup and goes down smoothly. 32In the end it bites like a snake and stings like a viper. 33Your eyes will see strange things, and your heart will speak in twists. 34You will be like a man lying down in the heart of the sea, like one lying at the top of the mast.
