Jeremiah 23:25 - Ellicott's Commentary On The Whole Bible

I have dreamed... — The words point to the form of the claim commonly made by the false prophets. Dreams took their place among the recognised channels of divine revelation (Genesis 40:8; Genesis 41:16; Joel 2:28; Daniel 7:1), but their frequent misuse by the false prophets brought them into discredit, and the teaching of Deuteronomy 13:1-5 accordingly brought the “dreamer of dreams” no less than the prophet to the test whether what he taught was in accordance with the law of Jehovah. The iteration of “I have dreamed” represents the affected solemnity with which the false prophets proclaimed their visions. Of the disparagement of dreams, consequent on this abuse, we have a striking example in Ecclesiastes 5:3, and later still in Sir. 34:1-7.
