He that hideth - This is a common case. How many, when full of resentment, and deadly hatred, meditating revenge and cruelty, and sometimes even murder, have pretended that they thought nothing of the injury they had sustained; had passed by the insult, etc.! Thus lying lips covered the malevolence of a wicked heart.
Better, He who hideth hatred is of lying lips. He who cherishes hatred, is either a knave, or a fool - a knave if he hides, a fool if he utters it.
