6. vine of low stature--not now, as before, a stately "cedar"; the
kingdom of Judah was to be prosperous, but not elevated.
branches turned toward him--expressing the fealty of Zedekiah as a
vassal looking up to Nebuchadnezzar, to whom Judah owed its peace and
very existence as a separate state. The "branches" mean his sons and the
other princes and nobles.
The roots . . . under him--The stability of Judah depended on Babylon.
The repetition "branches" and "springs" is in order to mark the
ingratitude of Zedekiah, who, not content with moderate prosperity,
revolted from him to whom he had sworn allegiance.
