Jeremiah 15:6,7 - Joseph Benson’s Commentary on the Old and New Testaments

Thou hast forsaken me, thou art gone backward God here, by more expressions of the same import with many that we have before met with, declares his steady resolution to destroy them for their apostacy from him; and represents himself as an angry prince or parent, that had frequently been provoked by a subject or child whom he had often resolved to punish, but out of his clemency, or upon the mediation of others, had altered his mind, and resolved to spare him; but afterward had met with so many fresh provocations that his patience was quite tired out, and he was determined to bear no longer. I will fan them with a fan Not a purging fan, to separate the chaff from them, but a scattering fan, to disperse and scatter them to all the winds, as Ezekiel expresses it, Ezekiel 5:12. In the gates of the land He alludes to a man standing in the gate of his thrashing-floor to fan and cleanse his corn. I will deprive them of children The words, of children, are not in the Hebrew, and are unnecessarily supplied: it may as well be of any, or all their comforts and good things. I will destroy my people The privilege they claim of being my people shall not protect them while they go on in their sinful courses.
