'Roots' in the Bible

It grew, and became a spreading vine of low stature, whose branches turned toward him, and its roots were under him: so it became a vine, and brought forth branches, and shot forth sprigs.

There was also another great eagle with great wings and many feathers: and behold, this vine did bend its roots toward him, and shot forth its branches toward him, from the beds of its plantation, that he might water it.

Say, Thus says the Lord Yahweh: Shall it prosper? shall he not pull up its roots, and cut off its fruit, that it may wither; that all its fresh springing leaves may wither? and not by a strong arm or many people can it be raised from its roots.
