You prophesy what you have not heard for I have not spoken
Thru the Bible: Ezekiel 13-16
Israel had their false prophets, and the generation which was alive during King Zedekiah's reign continually misinformed the people and predicted the complete opposite outcomes of their sinfulness than the words of Jeremiah and Ezekiel.
God, through Ezekiel addresses these false prophets.
I hope this study aids you in your pursuit of knowing God.
Blessings!
