“Son of man, prophesy against the prophets of Israel who are now prophesying. Tell those who prophesy out of their own imagination: Hear the word of the LORD!
The false prophets, who are here prophesied against, were some of them at Jerusalem (Jer 23:14): I have seen in the prophets at Jerusalem a horrible thing; some of them among the captives in Babylon, for to them Jeremiah writes (Jer 29:8), Let not your diviners, that be in the midst of you, deceive you.
Commenting on Ezekiel 13:1-9
Thus saith the Lord God, woe unto the foolish prophets,.... The false prophets, as the Targum; who are foolish, as all are who are not sent of God, and furnished by him with wisdom and knowledge, and who prophesy out of their own hearts; for what else but folly can proceed from thence?
that prophesy--namely, a speedy return to Jerusalem. out of . . . own hearts--alluding to the words of Jeremiah (Jer 23:16, Jer 23:26); that is, what they prophesied was what they and the people wished; the wish was father to the thought. The people wished to be deceived, and so were deceived.
