Jeremiah 50:36 - Matthew Poole's English Annotations on the Holy Bible

A sword is upon the liars; and they shall dote: the word here translated liars is by some translated bars, by some liars; and in the Hebrew it hath both significations; which makes some think it is to be understood of the chief men, who are the props, stays, and bars of a place, whose wisdom God threatens should fail them, so as they should dote, and show themselves fools. Others translating it liars as we do, understand it of their soothsayers and wizards, whom he calls liars, because they divined false, and saith they should dote, not foreseeing what should be. A sword is upon her mighty men; and they shall be dismayed: and though they were full of valiant, mighty men, yet their hearts should fail them when this day came, and all be destroyed amongst the rest.
