Jeremiah 28:15 - Ellicott's Commentary On The Whole Bible

Hear now, Hananiah... — The narrative leaves the time and place of the interview uncertain, but suggests an interval of some days between it and the scene in the Temple court just narrated. In the strength of the “word of the Lord” which had come to him, the prophet can now tell his rival that he is a pretender, claiming the gift of prophecy for his own purposes and that of his party. There is a strange significance in the fact that the same official title is applied to both the true and the false prophets.
