And it came to pass, when Ben-ha'dad heard this message, as he was drinking, he and the kings in the pavilions, that he said unto his servants, Set yourselves in array. And they set themselves in array against the city. As he was drinking he and the kings in the pavilions - booths made of branches of trees and brushwood. which were reared for kings in the camp, as they still are for Turkish Pashas or Agas in their expeditions (Keil, in loco; see also Chandler's 'Travails in Asia Minor,' p. 149).
Set yourselves in array - invest the city.
