'Roots' in the Bible

And its growth went on and it became a vine, low and widely stretching, whose branches were turned to him and its roots were under him: so it became a vine, putting out branches and young leaves.

And there was another eagle with great wings and thick feathers: and now this vine, pushing out its roots to him, sent out its branches in his direction from the bed where it was planted, so that he might give it water.

Say, This is what the Lord has said: Will it do well? will he not have its roots pulled up and its branches cut off, so that all its young leaves may become dry and it may be pulled up by its roots?
