'Beasts of the Field' in the Bible

Is my heritage to me as a speckled bird of prey? Are the birds of prey against her round about? Go ye, assemble all the beasts of the field; bring them to devour.

And now I have given all these lands into the hand of Nebuchadnezzar the king of Babylon, my servant. And the beasts of the field I have also given him to serve him.
