Charles Ellicott Commentary Jeremiah 23:30

"Therefore, behold, I am against the prophets, saith Jehovah, that steal my words every one from his neighbor." — Jeremiah 23:30 (ASV)

That steal my words ... — Another note of the counterfeit prophet is found in the lack of any living personal originality. The oracles of the dreamers were patchworks of plagiarism, and they borrowed, not as people might legitimately do (and as Jeremiah himself did) from the words of the great teachers of the past, but from people of their own time, as false and unreal as themselves. What we should call the “clique” of false prophets went on repeating each other’s phrases with a wearisome iteration. In “my words” we have, probably, the fact that they also, in part, decked out their teaching with the borrowed plumes of phrases from true prophets.
