John Trapp on Proverbs 18:4

Verſ. 4. The words of a mans mouth are as deep waters] Fitly are the words of the wiſe reſembled to waters (ſaith one) in as much as they both waſh the mindes of the hearers, that the foulneſs of ſin remain not therein, and water them in ſuch ſort that they faint not, nor wither by a drought and burning deſire of heavenly doctrine. Now theſe words of the wiſe are of two ſorts; ſome are as deep waters, and cannot eaſily bee fathomed, as Sampſons Riddles, and Solomons Apophthegms, ſo very much admired by the Queen of Sheba, 2 Chron. 9. ſome again are plain, and flow ſo eaſily as a flowing brook, that the ſimpleſt may underſtand them. The ſame may bee affirmed of the holy Scriptures (thoſe words of the wiſe, and their dark ſayings, Prov. 1.6.) The Scriptures ſaith one, are both text and gloſs, one place opens another, one place hath that plainly, that another delivers darkly. The Rabbius have one ſaying, That there is a mountain of ſenſe hangs upon every Apex of the word of God. And another they have, Nulla eſt objectio in lege quae non habet ſolutionem in latere, i. e. There is not any doubt in the Law, but may bee reſolved by ſome other Text. Parallel Scriptures caſt a mutual light one upon another; and is there not a thin veil laid over the word, which is more rarified by reading, and at laſt wholly worn away? A friend (ſaith Chryſoſtome) that is acquainted with his friend, will get out the meaning of a letter or phraſe, which another could not that is a ſtranger; So it is in the Scripture.
