'Madman' in the Bible

And Jehu came forth to the servants of his lord. And one said to him, Is all well? why came this madman to thee? And he said to them, Ye know the man, and his mind.

As a madman who casteth firebrands, arrows, and death,

Jehovah hath made thee priest in the stead of Jehoiada the priest, that there should be officers in the house of Jehovah, over every madman and self-made prophet, that thou shouldest put him in the stocks and in the shackles.
