The words of a talebearer are as wounds, and they go down into the innermost parts of the belly.   Burning lips and a wicked heart are like a potsherd covered with silver dross.   He that hateth dissembleth with his lips, and layeth up deceit within him;  When he speaketh fair, believe him not: for there are seven abominations in his heart.   Whose hatred is covered by deceit, his wickedness shall be shewed before the whole congregation.   Whoso diggeth a pit shall fall therein: and he that rolleth a stone, it will return upon him.   A lying tongue hateth those that are afflicted by it; and a flattering mouth worketh ruin.

Proverbs 26:22-28
