Proverbs 18:7-9

⁷The mouth of a fool is his destruction: and his lips are the ruin of his soul.

⁸The words of the double tongued are as if they were harmless: and they reach even to the inner parts of the bowels. Fear casteth down the slothful: and the souls of the effeminate shall be hungry.

⁹He that is loose and slack in his work, is the brother of him that wasteth his own works.
