Proverbs 23:31 in the King James Version
Look not thou upon the wine when it is red, when it giveth his colour in the cup, when it moveth itself aright.
Context
30 Those who stay long at the wine; those who go to seek out mixed wine.
31 Don’t look at the wine when it is red, when it sparkles in the cup, when it goes down smoothly.
32 In the end, it bites like a snake, and poisons like a viper.
