Smite a scorner, and the simple will beware: and reprove one that hath understanding, and he will understand knowledge.
– Proverbs 19:25
The scorner, the simple, and the man of understanding feature in this proverb. The distinction revolves around how correction is received. The word for scorner means to mock and scoff. Scorning is where the simple will end up if they do not receive correction and instruction (Proverbs 14:18). The word for simple means foolish, or naïve. Proverbs paints the simple as thoughtless and easily led (Proverbs 14:15; 15:21). Reproof alone will seldom correct the simple. They need stronger demonstration (Proverbs 21:11). The word for understanding means to separate mentally, or discern. Wise men have understanding and so instructions and reproofs are more effective and profitable for them (Proverbs 9:9-10; 15:5; 17:10).
