Proverbs 25:20
As he that taketh away a garment in cold weather, and as vinegar upon nitre, so is he that singeth songs to an heavy heart. As he that taketh away a garment in cold weather, and as vinegar upon nitre, so is he that singeth songs to an heavy heart.
Proverbs 25:20 belongs to the collection of Solomon's proverbs gathered by Hezekiah. It stands in a book made up of brief sayings that express familiar truths, often through comparison. Cheerful songs are unsuitable for someone who is deeply sorrowful and weighed down with a heavy heart. That mismatch is harmful and ill-fitted, like taking away a garment in cold weather or pouring vinegar on nitre.
