Proverbs 26:23-28

23Like a coating of silver dross on earthenware are fervent lips with an evil heart.

24Enemies disguise themselves with their lips, but in their hearts they harbor deceit.

25Though their speech is charming, do not believe them, for seven abominations fill their hearts.

26Their malice may be concealed by deception, but their wickedness will be exposed in the assembly.

27Whoever digs a pit will fall into it; if someone rolls a stone, it will roll back on them.

28A lying tongue hates those it hurts, and a flattering mouth works ruin.
