Proverbs 26:7

As a thorn goeth up into the hand of a drunkard, so is a parable in the mouth of fools.

So they shall make their own tongue to fall upon themselves: all that see them shall flee away.

Excellent speech becometh not a fool: much less do lying lips a prince.

And he said unto them, Ye will surely say unto me this proverb, Physician, heal thyself: whatsoever we have heard done in Capernaum, do also here in thy country.
