Sprüche 16:21

Four proverbs of wisdom with eloquence: 21 The wise in heart is called prudent, And grace of the lips increaseth learning. Elsewhere (Pro 1:5; Pro 9:9) הוסיף לקח means more than to gain learning, i.e., erudition in the ethico-practical sense, for sweetness of the lips (dulcedo orationis of Cicero) is, as to learning, without significance, but of so much the greater value for reaching; for grace of expression, and of exposition, particularly if it be not merely rhetorical, but, according to the saying pectus disertos facit, coming out of the heart, is full of mind, it imparts force to the instruction, and makes it acceptable. Whoever is wise of heart, i.e., of mind or spirit (לב = the N.T. νοῦς or πνεῦμα), is called, and is truly, נבון [learned, intelligent] (Fleischer compares to this the expression frequent in Isaiah, "to be named" = to be and appear to be, the Arab. du'ay lah); but there is a gift which highly increases the worth of this understanding or intelligence, for it makes it fruitful of good to others, and that is grace of the lips. On the lips (Pro 10:13) of the intelligent wisdom is found; but the form also, and the whole manner and way in which he gives expression to this wisdom, is pleasing, proceeding from a deep and tender feeling for the suitable and the beneficial, and thus he produces effects so much the more surely, and beneficently, and richly.

Note, 1. Those that have solid wisdom will have the credit of it; it will gain them reputation, and they shall be called prudent grave men, and a deference will be paid to their judgment. Do that which is wise and good and thou shalt have the praise of the same. 2. Those that with their wisdom have a happy elocution, that deliver their sentiments easily and with a good grace, are communicative of their wisdom and have words at will, and good language as well as good sense, increase learning; they diffuse and propagate knowledge to others, and do good work with it, and by that means increase their own stock. They add doctrine, improve sciences, and do service to the commonwealth of learning. To him that has, and uses what he has, more shall be given.
