Proverbs 26:6-12 introduces us to seven parables concerning the fool and his foolishness. I will address only the first two of the seven proverbs in today’s devotional and the balance in future months.
Proverbs 26:6 is a lesson in the folly of hiring a fool and placing your confidence in him as your messenger or representative. Why is it folly to send a fool as your ambassador? The employment of a fool as a messenger is the subject of verse 6.
Proverbs 26:6 – “He that sendeth a message [commandment; matter] by the hand of a fool cutteth off [cuts short] the feet [or legs] , and drinketh [consumes] damage [wrong; cruelty; violence].”
A fool cannot be trusted. He is silly by nature and his lack of discipline invariably haunts those who put their confidence in him. His foolishness both infuriates and exasperates. Solomon warned his son, a fool will leave in his wake damages that are not easily repaired. 
A man who trusts a fool figuratively cuts off his foot and has only himself to blame!
Proverbs 26:7 continues the challenge of engaging a fool, stating his deficiency in good sense means even a word of wisdom spoken by him is ill received.
Proverbs 26:7 – “The legs [hips; thighs] of the lame [one with a limp] are not equal: so is a parable [word of wisdom] in the mouth of fools.”
Solomon states what is a mundane observation—a man whose legs are not equal will walk with a limp. Nothing profound about that statement, except for its application: A lame man cannot hide his limp no more than a fool his stupidity. A fool stating a profundity is uncomely to anyone who hears him. Why? A proverb of wisdom in the mouth of a fool has no value.
Are you at a crossroads and long to be respected and valued? If that is you, please accept this blunt word of advice: Close your mouth and open your heart to truth and knowledge.
