Matthew Poole and continuators on Jeremiah 29:8

8 ¶ For thus saith the LORD of hosts, the God of Israel, Let not your prophets, and your diviners that be in the midst of you, deceive you, neither hearken to your dreams which ye cause to be dreamed .

The Lord knows that you have a company of false Prophets, that tell you other things, and promise you a sudden return out of your Captivity, pretending to know it by Revelation from God, or by divination, &c. or to have it discovered to them in dreams. It is the will of God that you should not hearken to them, for they do but deceive you, and ye are accessary to your own ruine, they see you are pleased to hear such stories, and that causeth them to dream, as chap. 5.31. The prophets prophesie falsly, and the priests bear rule by their means, and my people love to have it so, thus Isa. 30.10. They said to the seers, see not, and to the prophets, prophesie not to us right things, speak unto us smooth things, prophesie deceits. False teachers and guides of peoples souls are the greatest plague can befal a Nation, people from them expecting to hear the mind of God, and for the most part, people are accessary to their own ruine, in them it can indeed hardly be imagined, what other temptation, persons whose office it is to reveal the mind of God, should have to do otherwise, but the humouring and pleasing of a corrupt people, who through their fondness of their lusts are not patient of sound Doctrine, so as though the Church of God hath in all Ages been troubled with dreamers, yet it is a wicked people that causeth them to dream.
