Adam Clarke on Psalms 31:10

My life is spent with grief - My life is a life of suffering and distress, and by grief my days are shortened. Grief disturbs the functions of life, prevents the due concoction of food, injures the digestive organs, destroys appetite, impairs the nervous system, relaxes the muscles, induces morbid action in the animal economy, and hastens death. These effects are well expressed in the verse itself.

My years with sighing - אנחה anachah. This is a mere natural expression of grief; the very sounds which proceed from a distressed mind; an-ach-ah! common, with little variation, to all nations, and nearly the same in all languages. The och-och-on of the Irish is precisely the same sound, and the same sense. Thousands of beauties or this kind are to be found in the sacred language.
