Another beast, viz. the Medes and Persians, a fierce, grim, ravenous creature, and barbarously cruel, especially the mountainous part, as of Caucasus, Armenia, and Media by The Caspian Sea near the Tartars, and that which borders upon the Mogul, the Usbecks, and the Sasbuts; read Isaiah 13:17,18 Jeremiah 51:48,53, called spoilers. See Jeremiah 51:11, &c. Thus God sent in the northern bears upon Babylon to devour flesh. See how God calls them against Babylon, Jeremiah 51:20-23,27,28; he reckons Ararat, Minni, and Ashchenaz, and the Medes, i.e. Armenia, Parthia, Hyrcania, &c., the rough northern hungry bears. On one side, i.e. the north side; for the Mede first arose and sent to Cyrus the Persian to come in and assist him against the Assyrian, and made him general. It had three ribs in the mouth of it: several of the Babylonian subjects revolted from the Babylonian, (and all these made the three ribs,) as the Hyrcanians, and Gobrias.
