In all cases the successful lie relies on a falsehood being received as the truth, but from the perspective of the victim lies take two forms: undisguised, out-in-the-open lies, which he knows are false, and lies that pretend to be something other than what they are, smooth lies that appear to speak peace; both types are considered in this verse. The obvious lie is designed to do harm and, from the perspective of the victim, does not bother to hide from view.
