Adam Clarke on Proverbs 12:11

He that tilleth his land - God's blessing will be in the labor of the honest agriculturist.

But he that followeth vain persons - He who, while he should be cultivating his ground, preparing for a future crop, or reaping his harvest, associates with fowlers, coursers of hares, hunters of foxes, or those engaged in any champaign amusements, is void of understanding; and I have known several such come to beggary.

To this verse the Septuagint add the following clause: 'ov estin en oinwn diatribaiv, en toiv eautou ocurwmasi kataleiqei atimian. "He who is a boon companion in banquets, shall leave dishonor in his own fortresses." This has been copied by the Vulgate and the Arabic. That is The man who frequents the ale-house enriches that, while he impoverishes his own habitation.
