to be out of one's right mind, or to act like it: madness that shows itself in how a person behaves.
This is a word about madness other people can see. It never describes a private mood or a quiet inner state. It describes someone whose behavior has come apart in the open, so that anyone watching says "that man is out of his mind." Every one of its seven appearances is somebody's verdict on how another person is acting.
It turns up in three settings:
- as a curse, when Deuteronomy warns that a nation crushed by disaster will be driven out of its mind by what it is forced to watch;
- as an insult, when royal officers, a hostile priest, and a jeering crowd all call a prophet a madman;
- as a disguise, when David escapes the king of Gath by scratching at the city gate and letting spit run down into his beard.
The insult is the striking part. Three of the six verses that use the word aim it at prophets, which says something about how prophecy looked from the outside: the trances, the shouting, the strange acted-out signs. The Bible reports the sneer without agreeing with it. In 2 Kings the "madman" being mocked has just anointed the next king of Israel, and everything he said comes true.
Two nearby words help fix its edges. A fool (אֱוִיל) is someone whose judgment and choices are bad, and Hosea sets that word right beside this one; this word is not about bad judgment at all, but about a mind that has stopped working. A broader verb (הָלַל) covers raving and reeling of many kinds, and it is the one the narrator picks for David's act in 1 Samuel 21:13, while the king of Gath reaches for this word instead. The matching noun (שִׁגָּעוֹן) names madness as a condition rather than naming the person who has it.
