'Devoted' in the Bible

Lo, I am sending, and have taken all the families of the north -- an affirmation of Jehovah -- even unto Nebuchadrezzar king of Babylon, My servant, and have brought them in against this land, and against its inhabitants, and against all these nations round about, and have devoted them, and appointed them for an astonishment, and for a hissing, and for wastes age-during.
