John Gill Reformed Baptist @doctorgill

For the drunkard and the glutton shall come to poverty,.... They consuming their substance upon their bellies, in eating and drinking; see Pro 21:17; and drowsiness shall clothe a man with rags; excessive eating and drinking brings drowsiness on men, unfits them for business, and makes them idle and slothful; and spending all on their bellies, they have nothing for their backs, and are clothed in rags; see Pro 24:33.
