Proverbs 26:23-26

23Like a coating of silver dross on earthenware are fervent Hebrew; Septuagint smooth 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.
