Jeremiah 23:25 - Matthew Poole's English Annotations on the Holy Bible

Visions and dreams were two usual ways by which under the law God made himself known of old to his prophets, making them sometimes, being awake, to hear a voice; sometimes attended with, and proceeding upon, some visible appearance, sometimes not: at other times causing them being asleep, to dream; and in their sleep revealing to them, as in a dream, what his will was they should declare and publish to his people. These false prophets speaking what came into their own heads, and suited their own lust, or the lusts of a debauched people to whom they spake, would pretend that God had revealed to them what they so published in a dream; not in the mean time considering God took notice of these their little arts by which they cheated the people. But saith God, I am a God that know afar off as well as at hand, and I have heard what they say, prophesying lies as from me, and pretending that I had in dreams revealed them to them.
