Adam Clarke on 1 Corinthians 12:26

And whether one member suffer - As there is a mutual exertion for the general defense, so there is a mutual sympathy. If the eye, the hand, the foot, etc., be injured, the whole man grieves; and if by clothing, or any thing else, any particular member or part is adorned, strengthened, or better secured, it gives a general pleasure to the whole man.
