Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him.
– Proverbs 22:15
The word for foolishness is common in Proverbs, occurring about 19 times. The word includes the ideas of silliness and stubbornness. Solomon gives the true born-that-way argument. Children come into the world ignorant and obstinate. The heart, or mind, is tied up in foolishness. Wisdom teaches instruction, correction, and chastisement are needed to grow a person in wisdom. How they are progressing in wisdom will be evident in their response to these (Proverbs 1:5, 7, 22, 29-30; 15:5). Chastisement comes through the rod of correction, emphasizing the need for more than just words to drive out folly. Parents must be diligent to instruct, correct, and chastise while their fools are young (Proverbs 13:24; 19:18). To neglect or withhold such correction is a failure to love the child and to reinforce their folly (Proverbs 23:13-14; 29:15). A fool who matures in his folly becomes practically incorrigible (Proverbs 27:22).
