a wide outer cloak: the ample wrap thrown on over the rest of a person's clothing, large or fine enough to mark out the one wearing it
The name of this garment is really a word about size. It belongs to a family of Hebrew words meaning wide, ample, and grand, the same family that gives the adjective for mighty or majestic (אַדִּיר). So the cloak is, literally, "the wide one": the big outer piece a person threw on over everything else, and by the same token the impressive one.
That is why a single word stretches across garments a modern reader would never group together:
- a pelt so shaggy that a hairy newborn could be compared to it
- an imported cloak from Babylon, taken from plunder a man had been forbidden to touch
- the cloak Elijah wrapped his face in, threw over Elisha, and struck the Jordan with
- the robe of state the king of Nineveh pulled off before sitting down in ashes
What holds them together is not the material but the amplitude. Each is the outermost and most conspicuous thing its wearer has on.
The most famous of them is the prophet's cloak. Elijah's turns up at every hinge of his story, and after he is taken away Elisha picks it up and repeats the miracle at the river with it. By the time of Zechariah the rough hair version was so recognizable as prophetic dress that a false prophet could put one on as a costume. How much the cloth itself carried is argued: Elisha asks for a double share of Elijah's spirit rather than for the cloak, and even holding it he has to call on the God of Elijah before the water opens.
Hebrew has other garment words that do different work. The long robe of office (מְעִיל) is the one that gets torn in scenes about a kingdom being taken away, and the ordinary outer wrap (שִׂמְלָה) is the everyday cloth a poor man also slept under. This word is the one chosen when the garment is meant to look ample and important.
Nuances
What the cloak actually does in the Elijah and Elisha scenes (1 Kings 19:13, 19; 2 Kings 2:8, 13, 14): whether it conveys prophetic power and office, marks Elisha as heir, or signals Elijah's decommissioning.

- minorityThe cloak is never invested with power: it appears only at moments of Elijah's decline, Elisha asks for a double portion of the spirit rather than for the garment, and the Jordan parts only when Elisha invokes the God of Elijah.; Christina M.
