Adam Clarke on Luke 14:12

Call not thy friends, etc. - Our Lord certainly does not mean that a man should not entertain at particular times, his friends, etc.; but what he inculcates here is charity to the poor; and what he condemns is those entertainments which are given to the rich, either to flatter them, or to procure a similar return; because the money that is thus criminally laid out properly belongs to the poor.
