'Tree' in the Bible

As to the visions of my head on my bed, I was looking, and lo, a tree in the midst of the earth, and its height is great:

become great hath the tree, yea, strong, and its height doth reach to the heavens, and its vision to the end of the whole land;

He is calling mightily, and thus hath said, Cut down the tree, and cut off its branches, shake off its leaves, and scatter its budding, move away let the beast from under it, and the birds from off its branches;

The tree that thou hast seen, that hath become great and strong, and its height doth reach to the heavens, and its vision to all the land,

and that which the king hath seen -- a sifter, even a holy one, coming down from the heavens, and he hath said, Cut down the tree, and destroy it; but the stump of its roots leave in the earth, even with a band of iron and brass, in the tender grass of the field, and with the dew of the heavens it is wet, and with the beast of the field is his portion, till that seven times pass over him.

And that which they said -- to leave the stump of the roots of the tree; thy kingdom for thee abideth, after that thou knowest that the heavens are ruling.
