Proverbs 26:23-28

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.
