John Trapp on Jeremiah 29:8

Ver. 8. Let not your Prophets and your diviners] Your deceivers indeed, which were alſo in Babylon as well as at Jeruſalem: for all places are full of them, and ſo is hell too. But beware of theſe dogs, beware of evil workers, Philip. 3.2. three of them, the moſt active, no doubt, are here noted and noticed, ver. 21.23. with a charge in this text, Ne committitote ut decipiant vos, See that they deceive you not. The body ſhould be kept, ſay Phyſicians, in habitu athletico, in a vigorous and healthy temper, able to oppoſe infections. Think the ſame of the ſoul.

Neither harken to your dreams] Yours, becauſe you itch after them, liſten to them, pray dearly for them.
