Proverbs 23:32 in the World English Bible
In the end, it bites like a snake, and poisons like a viper.
Context
31 Look not thou upon the wine when it is red, when it giveth his colour in the cup, when it moveth itself aright.
32 At the last it biteth like a serpent, and stingeth like an adder.
33 Thine eyes shall behold strange women, and thine heart shall utter perverse things.
