With Löwenstein, Hitzig, and others, it is inadmissible to regard ושׁבט as a second subject to תּמּצא. The mouth itself, or the word of the mouth, may be called a rod, viz., a rod of correction (Isa 11:4); but that wisdom and such a rod are found on the lips of the wise would be a combination and a figure in bad taste. Thus 13b is a clause by itself, as Luther renders it: “but a rod belongs to the fool's back;” and this will express a contrast to 13a, that while wisdom is to be sought for on the lips of the man of understanding (cf. Mal 2:7), a man devoid of understanding, on the contrary, gives himself to such hollow and corrupt talk, that in order to educate him to something better, if possible, the rod must be applied to his back; for, according to the Talmudic proverb: that which a wise man gains by a hint, a fool only obtains by a club. The rod is called שׁבט, from שׁבט, to be smooth, to go straight down (as the hair of the head); and the back גּו, from גּוה, to be rounded, i.e., concave or convex.
Verse 14
Pro 10:14 14 Wise men store up knowledge; But the mouth of the fool is threatening destruction.
Ewald, Bertheau, Hitzig, Oetinger: “The mouth of the fool blunders out, and is as the sudden falling in of a house which one cannot escape from.” But since מחתּה is a favourite Mishle-word to denote the effect and issue of that which is dangerous and destructive, so the sense is perhaps further to be extended: the mouth of the fool is for himself (Pro 13:3) and others a near, i.e., an always threatening and unexpectedly occurring calamity; unexpectedly, because suddenly he blunders out with his inconsiderate shame-bringing talk, so that such a fool's mouth is to every one a praesens periculum. As to יצפּנוּ, it is worthy of remark that in the Beduin, Arab. dfn, fut. i, signifies to be still, to be thoughtful, to be absorbed in oneself (vid., Wetstein on Job, p. 281). According to Codd. and editions, in this correct, וּפי־ is to be written instead of אויל uwpiy; vid., Baer's Torath Emeth, p. 40.
Verse 15
A pair of proverbs regarding possession and gain.
Regarding possession:
The rich man's wealth is his strong city;
The destruction of the poor is their poverty.
The first line = Pro 18:11. One may render the idea according to that which is internal, and according to that which is external; and the proverb remains in both cases true. As עז may mean, of itself alone,
