Son of man, prophesy against the prophets of Israel that prophesy, and say thou unto them that prophesy out of their own hearts, Hear ye the word of the LORD;
Say ... unto them that prophesy - namely, a speedy return to Jerusalem.
Out of their own hearts - alluding to the words of Jeremiah (Jeremiah 23:16; Jeremiah 23:26); i:e., 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. They were inexcusable, because they had among them true prophets (who "spake" not their own thoughts, but "as they were moved by the Holy Spirit," 2 Peter 1:21), whom they might have known to be such, but they did not wish to know (John 3:19).
