What the Bible says about Lying Lips
(From Forerunner Commentary)
Lying lips create a false sense of security and cunningly hide the reality of a deception that will bring loss and pain. Though his voice sounds gracious, the liar is full of countless wickedness. He is particularly wicked by selling himself as a benefactor while intending to do evil. This is the kind of heart involved in financial scams that promise large profits in return for small investment.
