A little history .. cherubim (wind demons) and seraphim (fire demons) are part of the retinue of Yahweh in the polytheistic worship in the Canaanite temple in Jerusalem, before the reign of King Josiah (before the Babylonian Exile). See The Hebrew Goddess by Raphael Patai. Per natural phenomena ... cherubim are dust devils of the ME sort, and seraphim are fire devils (from strong brush fires). See them on YouTube.
Judaism first tried to become monotheistic at the time of King Josiah, but was overtaken by Egyptian and Babylonian opposition. Ezra and Nehemiah, after the Persian took over, reestablished Judaism (OT) as we currently know it, after returning from Babylon ... as Persian quislings. The majority of people still in Israel/Judah were polytheists ... and naturally were the opposition to be overcome by the new dispensation from the Shah of Persia. This is why the Shah comes off so well in the Book of Esther.
