Proverbs 26:7 - Matthew Poole's English Annotations on the Holy Bible

The legs of the lame are not equal, Heb. As (which note of similitude is plainly understood from the particle so in the following clause) the legs of the lame are lifted up, to wit, in going, or rather in dancing, which is done with great inequality and uncomeliness. So is a parable in the mouth of fools; no less absurd and indecent are wise and pious speeches from a foolish and ungodly man, whose actions grossly contradict them, whereby he makes them contemptible, and himself ridiculous.
