'Falsehood' in the Bible

“How can you say, ‘We are wise,And the law of the Lord is with us [and we are learned in its language and teachings]’?Behold, [the truth is that] the lying pen of the scribesHas made the law into a lie [a mere code of ceremonial observances].

Every man has become [like a brute] irrational and stupid, without knowledge [of God];Every goldsmith is shamed by his carved idols;For his molten images are frauds and lies,And there is no breath in them.

“This is your destiny, the portion [of judgment] measured to youFrom Me,” says the Lord,“Because you have forgotten MeAnd trusted in [pagan] lies [the counterfeit gods, and the pretense of alliance].”

How long [shall this state of affairs continue]? Is there anything in the hearts of the prophets who prophesy falsehood, even these prophets of the deception of their own heart,
