Ecclesiastes 7:3,4 - Joseph Benson’s Commentary on the Old and New Testaments

Sorrow is better than laughter Either sorrow for sin, or even sorrow on other accounts; for by the sadness of the countenance Sadness seated in the heart, but manifested in the countenance; the heart is made better Is more weaned from the lusts and vanities of this world, by which most men are ensnared and destroyed; and more quickened to seek after and embrace that true and everlasting happiness which God offers to them in his word. The heart of the wise is in the house of mourning Even when their bodies are absent. They are constantly, or very frequently, meditating upon serious things, such as death and judgment, the vanity of this life, and the reality and eternity of the next; because they know that these thoughts, though they be not grateful to man's carnal mind, yet are absolutely necessary and highly profitable, and productive of great comfort in the end, which every wise man most regards. But the heart of fools is in the house of mirth Their minds and affections are wholly set upon feasting, jollity, and merriment, because, like fools and irrational animals, they regard only their present delight, and mind not how dearly they must pay for it.
