Ecclesiastes 5:12 - Joseph Benson’s Commentary on the Old and New Testaments

The sleep of a labouring man is sweet Because he is free from those cares and fears wherewith the minds of rich men are often distracted, and their sleep disturbed; whether he eat little For his weariness disposes him to sleep; or much In which case his healthful constitution, and laborious course of life, prevent those crudities and indigestions which ofttimes break the sleep of rich men: but the abundance of the rich Hebrew, השׂבע, the fullness, either, 1st, Of his diet, which commonly discomposes the rich man's stomach, and hinders his rest: or, 2d, Of his wealth, which is generally attended with many perplexing cares, both by day and night. The Hebrew word is used in Scripture both ways, and probably is here intended to include both significations.
