John Gill Commentary Ezekiel 13:17

"And thou, son of man, set thy face against the daughters of thy people, that prophesy out of their own heart; and prophesy thou against them," — Ezekiel 13:17 (ASV)

Likewise, you son of man, set your face against the daughters
of your people
The false prophetesses; for as there were women in some ages, who had the true spirit of prophecy, as Miriam, Deborah, and Huldah, (Exodus 15:20) (Judges 4:4) (2 Kings 22:14) ; so there were some that pretended to it, who has it not, as Noadiah in the times of Nehemiah, (Nehemiah 6:14) ; and such there were in the times of Ezekiel; against whom he is bid to set his face, and look them out of countenance, and make them ashamed; who, contrary to the modesty of the sex, had impudently taken upon them to prophesy to the people; and such have been since in the times of the Gospel, as Jezebel, (Revelation 2:20) ; and Prisca, Maximilia, Quintilia, and others:

who prophesy out of their own heart ;
as the men did, (Ezekiel 13:2) ; what their own hearts suggested to them; what came into their minds, and their own fancies and imaginations led them to; what was according to their carnal affections and desires, and agreeable to those that heard them: and prophesy you against them ;
declare their prophecies false; warn the people from giving heed to them; and foretell what shall befall them for deceiving the people.
