“And behold another beast, a second, like to a bear, and it raised up itself on one side, and it had three ribs in the mouth of it between the teeth of it: and they said thus unto it, Arise, devour much flesh.”
King James Version (KJV)
7:5 Another beast - The Mede's and Persians, a fierce, ravenous creature. On one side - The north side; for the Mede first arose and sent to Cyrus the Persian to come and assist him against the Assyrian. Three ribs - Several of the Babylonian subjects revolted, and all these made the three ribs.
