Proverbs 22:15

15 Folly is bound to the heart of a child; The rod of correction driveth it forth. Folly, i.e., pleasure in stupid tricks, silly sport, and foolish behaviour, is the portion of children as such; their heart is as yet childish, and folly is bound up in it. Education first driveth forth this childish, foolish nature (for, as Menander says: Ὁ μὴ δαρεὶς ἄνθρωπος οὐ παιδεύεται), and if effects this when it is unindulgently severe: the שׁבט מוּסר (vid., Pro 23:13) removeth אוּלת from the heart, for it imparts intelligence and makes wise (Pro 29:15). The lxx is right in rendering 16a: ἄνοια ἐξῆπται (from ἐξάπτειν) καρδίας νέου; but the Syr. has "here mangled the lxx, and in haste has read ἀνοίᾳ ἐξίπταται: folly makes the understanding of the child fly away" (Lagarde).

We have here two very sad considerations: - 1. That corruption is woven into our nature. Sin is foolishness; it is contrary both to our right reason and to our true interest. It is in the heart; there is an inward inclination to sin, to speak and act foolishly. It is in the heart of children; they bring it into the world with them; it is what they were shapen and conceived in. It is not only found there, but it is bound there; it is annexed to the heart (so some); vicious dispositions cleave closely to the soul, are bound to it as the cion to the stock into which it is grafted, which quite alters the property. There is a knot tied between the soul and sin, a true lover's knot; they two became one flesh. It is true of ourselves, it is true of our children, whom we have begotten in our own likeness. O God! thou knowest this foolishness. 2. That correction is necessary to the cure of it. It will not be got out by fair means and gentle methods; there must be strictness and severity, and that which will cause grief. Children need to be corrected, and kept under discipline, by their parents; and we all need to be corrected by our heavenly Father (Heb 12:6, Heb 12:7), and under the correction we must stroke down folly and kiss the rod.

22:15 Wisdom is learned, not inherited or innate. It takes discipline to change foolishness into wisdom.
