And the Lord God said unto the serpent, Because thou hast done this, thou [art] cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life: (3:14)

--Isaiah--

The wolf and the lamb shall feed together, and the lion shall eat straw like the bullock: and dust [shall be] the serpent's meat. They shall not hurt nor destroy in all my holy mountain, saith the Lord. (65:25)

--Micah--

They shall lick the dust like a serpent, they shall move out of their holes like worms of the earth: they shall be afraid of the Lord our God, and shall fear because of thee. (7:17)
