Matthew Poole and continuators on Proverbs 21:11

11 * When the scorner is punished, the simple is made wise: and when the wise is instructed , he receiveth knowledg.

The honest or plainhearted man, as Chap. 19. 25. where this whole verse for the substance of it is contained and explained.

Or, prospers, as this word is used, Prov. 17. 8. and elsewhere. So the sense of the verse is, The simple learn Wisdom, both from the punishment of wicked men, and from the prosperity▪of good men.
