18:2 A fool hath no delight in understanding, but that his heart may {b} reveal itself.
(b) That is, that he may talk licentiously of whatever comes to mind.
18:2 Understanding - In getting sound and saving, knowledge. The discovery - In uttering that folly and wickedness which is in his heart.
18:1 If we would get knowledge and grace, we must try all methods of improving ourselves. 2. Those make nothing to purpose, of learning or religion, whose only design is to have something to make a show with. 3. As soon as sin entered, shame followed.
