It is better to hear the rebuke of the wise, than for a man to hear the song of fools. Ecclesiastes 7:5 (KJV)
‘The rebuke of the wise,’ perhaps follows from the previous verse – the understanding of a wise man. Wisdom is understood as an understanding of the reality of sin, suffering, death, et cetera. To be reminded of such reality seems to be a thing of wisdom, and of the wise that is worth listening to. The song of the fools seems to be a contradiction and an ignorance of such reality. To quote Henry, “that it is much better for us to have our corruptions mortified by the rebuke of the wise than to have them gratified by the song of fools.”
