John Gill Commentary Proverbs 4:17

"For they eat the bread of wickedness, And drink the wine of violence." — Proverbs 4:17 (ASV)

For they eat the bread of wickedness Either that is gotten by wicked and unlawful means, or wickedness itself is bread unto them; it is that to their minds as bread is to their bodies; they feed upon it with as much eagerness, appetite, gust, and pleasure; it is a sweet morsel to them; it is meat, drink, sleep, and everything to them; they take the highest satisfaction and the utmost delight in it;

and drink the wine of violence : either that which is obtained by rapine and violence; or they as greedily commit such acts of oppression and injury as a man drinks a glass of wine; they do not drink up iniquity like water only, but even like wine, the most generous and delicious.

Wherefore all society with such men should be avoided.
