6 He that sendeth a message by the hand of a fool cutteth off [his own] feet, [and] drinketh damage. 7 The legs of the lame hang loose; so is a proverb in the mouth of fools. 8 As a bag of gems in a stoneheap, so is he that giveth honour to a fool. 9 [As] a thorn goeth up into the hand of a drunkard, so is a proverb in the mouth of fools.
Matthew Henry's Commentary on Proverbs 26:6-9

(Read Proverbs 26:6-9)
Fools are not fit to be trusted, nor to have any honour. Wise sayings, as a foolish man delivers and applies them, lose their usefulness.
