'Teeth' in the Bible

In those days they will no longer say, The fathers have been tasting bitter grapes and the children's teeth are put on edge.

But everyone will be put to death for the evil which he himself has done: whoever has taken bitter grapes will himself have his teeth put on edge.

Nebuchadrezzar, king of Babylon, has made a meal of me, violently crushing me, he has made me a vessel with nothing in it, he has taken me in his mouth like a dragon, he has made his stomach full with my delicate flesh, crushing me with his teeth.
