Foams

And wheresoever he taketh him,
he teareth him:
and he foameth,
and gnasheth with his teeth,
and pineth away:
and I spake to thy disciples that they should cast him out;
and they could not.
Mark 9:18 KJV

And,
lo,
a spirit taketh him,
and he suddenly crieth out;
and it teareth him that he foameth again,
and bruising him hardly departeth from him.
Luke 9:39 KJV
