'Madman' in the Bible

so he pretended to be insane in their presence. He acted like a madman around them, scribbling on the doors of the gate and letting saliva run down his beard.

Again the watchman reported, “He reached them but hasn’t started back. Also, the driving is like that of Jehu son of Nimshi—he drives like a madman.”

Like a madman who throws flaming darts and deadly arrows,

‘The Lord has appointed you priest in place of Jehoiada the priest to be the chief officer in the temple of the Lord, responsible for every madman who acts like a prophet. You must confine him in the stocks and an iron collar.

Are they servants of Christ?I’m talking like a madman—I’m a better one:with far more labors,many more imprisonments,far worse beatings, near death many times.
