Proverbs 20:26 - Matthew Poole's English Annotations on the Holy Bible

A wise king, who seriously minds his duty and his true interest, scattereth the wicked; breaks their companies and confederacies, and forceth them to flee several ways for their own safety; driveth them from his presence, and from the society of honest men, as the chaff is by the husbandman separated from the corn, and driven away by the wind, of which this Hebrew word is commonly used, and to which the next clause hath some reference. Bringeth the wheel over them, as the cart-wheel was anciently turned over the sheaves to beat the corn out of them, Isaiah 28:27,28. He punisheth them severely, as their offences deserve. This or such-like punishments were not unusual among the Eastern nations, as we may gather from 2 Samuel 8:2, 2 Samuel 12:31 Amos 1:3.
