Jeremiah develops the idea of prophets who are deluded [23:25-32], contrasting the power of the genuine with with the worthlessness of the counterfeit. He finishes with an attack on the cheapening of the Lord’s word, where it is everywhere sought but only to be tamed, and where everyone’s claim to have it makes it impossible to hear a true word when it comes. –Gordon McConville (New Bible Commentary, 691)
