The LORD answered, “The people of Israel and Judah have done horrible things. Their country is filled with murderers, and Jerusalem itself is filled with violence. They think that I have deserted them, and that I can't see what they are doing.
Whenever the demon attacks my son, it throws him to the ground and makes him foam at the mouth and grit his teeth in pain. Then he becomes stiff. I asked your disciples to force out the demon, but they couldn't do it.”
A demon often attacks him and makes him scream. It shakes him until he foams at the mouth, and it won't leave him until it has completely worn the boy out.
