“And it grew, and became a spreading vine of low stature, whose branches turned toward him, and the roots thereof were under him: so it became a vine, and brought forth branches, and shot forth sprigs.”
King James Version (KJV)
17:6 Of low stature - They grew and flourish, while they owned their state tributary to Babylon. Toward him - Nebuchadnezzar as their protector, and sovereign lord. The roots - All the firmness, fruitfulness, and life of this state, was in subjection to him.
