Kommentar zu Jirmejahu 23:30

those who steal My wards from one another They have spies who spy upon the true prophets, who listen to their expression with which they prophesy and say false prophecies with that same expression, as Hananiah son of Azzur did. He heard Jeremiah prophesying in the upper marketplace, “Behold I break the bow of Elam,” and he prophesied in the lower marketplace, “I have broken the yoke of the king of Babylon” (28:2), as our Rabbis wrote in Sanhedrin 89a.
