Proverbs 26:23-28

23Like a [common] clay vessel covered with the silver dross [making it appear silver when it has no real value] Are burning lips [murmuring manipulative words] and a wicked heart.

24He who hates, disguises it with his lips, But he stores up deceit in his heart.

25When he speaks graciously and kindly [to conceal his malice], do not trust him, For seven abominations are in his heart.

26Though his hatred covers itself with guile and deceit, His malevolence will be revealed openly before the assembly.

27Whoever digs a pit [for another man’s feet] will fall into it, And he who rolls a stone [up a hill to do mischief], it will come back on him.

28A lying tongue hates those it wounds and crushes, And a flattering mouth works ruin.
