7:1-8 This vision contains the same prophetic representations with Nebuchadnezzar's dream. The great sea agitated by the winds, represented the earth and the dwellers on it troubled by ambitious princes and conquerors. The four beasts signified the same four empires, as the four parts of Nebuchadnezzar's image. Mighty conquerors are but instruments of God's vengeance on a guilty world.

Media is the lower side, passiveness; Persia, the upper, active element [Auberlen]. The three ribs in its mouth are Media, Lydia, and Babylon, brought under the Persian sway. Rather, Babylon, Lydia, and Egypt, not properly parts of its body, but seized by Medo-Persia [Sir Isaac Newton]. Called "ribs" because they strengthened the Medo-Persian empire. "Between its teeth," as being much grinded by it.
