12 It happened, when Ben Hadad heard this message, as he was drinking, he and the kings, in the pavilions, that he said to his servants, "Prepare to attack!" They prepared to attack the city.
*Minor differences ignored. Grouped by changes, with first version listed as example.
Pavilions - "Booths" (Genesis 33:17 margin; Leviticus 23:42; Jonah 4:5). The term seems to be properly applied to a stationary "booth" or "hut," as distinguished from a moveable "tent." On military expeditions, and especially in the case of a siege, such "huts" were naturally constructed to shelter the king and his chief officers.
In the pavilions - This word comes from papilio, a butterfly, because tents, when pitched or spread out, resembled such animals; partly because of the mode of their expansion, and partly because of the manner in which they were painted.
Set yourselves in array - The original word, שימו simu, which we translate by this long periphrasis, is probably a military term for Begin the attack, Invest the city, Every man to his post, or some such like expression.
And it came to pass, when Benhadad heard this message (as he was drinking, he and the kings in the pavilions),.... Though it was at noon, or before, 1-Kings 20:16, which shows that he and they were addicted to intemperance:
that he said unto his servants; some of the principal officers of his army:
set yourselves in array; prepare for battle, betake yourselves to your arms, invest the city at once, and place the engines against it to batter it down:
and they set themselves in array against the city; besieged it in form, at least prepared for it; for it seems after all that it was not properly done.
The proud Syrians were beaten, and the despised Israelites were conquerors. The orders of the proud, drunken king disordered his troops, and prevented them from attacking the Israelites. Those that are most secure, are commonly least courageous. Ahab slew the Syrians with a great slaughter. God often makes one wicked man a scourge to another.
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].
Set yourselves in array--Invest the city.
After this reply of Ahab, Benhadad gave command to attack the city, while he was drinking with his kings in the booths. סכּות are booths made of branches, twigs, and shrubs, such as are still erected in the East for kings and generals in the place of tents (vid., Rosenmller, A. u. N. Morgenl. iii. pp. 198-9). שׂימוּ: take your places against the city, sc. to storm it (for שׂים in the sense of arranging the army for battle, see 1-Samuel 11:11 and Job 1:17); not οἰκοδομήσατε χάρακα (lxx), or place the siege train.
