'Madman' in the Bible

Achish said to his servants, "Look at this madman! Why did you bring him to me?

When Jehu rejoined his master's servants, they asked him, "Is everything all right? Why did this madman visit you?" He replied, "Ah, it's not important. You know what kind of man he is and the kinds of things he says."

Like a madman who shoots firebrands and deadly arrows,

The prophet is considered a fool -- the inspired man is viewed as a madman -- because of the multitude of your sins and your intense animosity.
