Proverbs 26:7

The legs of the lame are not equal: so is a parable in the mouth of fools.

The legs of the lame are not equal, [ dalyuw (H1809 ), from daalah (H1802 )] - literally, rise up, or are elevated: one leg is longer than the other; so a parable (a sententious maxim) in the mouth of fools.

The parable halts, and is not consistent on all sides with itself, and is still less so with the character of him who speaks it. The parabolic style needs especial acuteness: the fool has regard neither to the time, nor place, nor sense. nor application, and so misses the scope of the proverb which he quotes ( Sir 20:20 , 'A wise sentence shall be rejected when it cometh out of a fool's mouth, for he will not speak it in due season').
