3 Kings (1 Kings) 20:1
kg1 20:1BEN-HADAD BESIEGES SAMARIA. (Kg1 20:1-12)
Ben-hadad the king of Syria--This monarch was the son of that Ben-hadad who, in the reign of Baasha, made a raid on the northern towns of Galilee (Kg1 15:20). The thirty-two kings that were confederate with him were probably tributary princes. The ancient kings of Syria and PhÅnicia ruled only over a single city, and were independent of each other, except when one great city, as Damascus, acquired the ascendency, and even then they were allied only in time of war. The Syrian army encamped at the gates and besieged the town of Samaria.
3 Kings (1 Kings) 20:2
kg1 20:2Thus said Ben-hadad, Thy silver and thy gold is mine--To this message sent him during the siege, Ahab returned a tame and submissive answer, probably thinking it meant no more than an exaction of tribute. But the demand was repeated with greater insolence; and yet, from the abject character of Ahab, there is reason to believe he would have yielded to this arrogant claim also, had not the voice of his subjects been raised against it. Ben-hadad's object in these and other boastful menaces was to intimidate Ahab. But the weak sovereign began to show a little more spirit, as appears in his abandoning "my lord the king" for the single "tell him," and giving him a dry but sarcastic hint to glory no more till the victory is won. Kindling into a rage at the cool defiance, Ben-hadad gave orders for the immediate sack of the city.
3 Kings (1 Kings) 20:12
kg1 20:12as 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.
3 Kings (1 Kings) 20:13
kg1 20:13THE SYRIANS ARE SLAIN. (Kg1 20:13-20)
behold, there came a prophet unto Ahab--Though the king and people of Israel had highly offended Him, God had not utterly cast them off. He still cherished designs of mercy towards them, and here, though unasked, gave them a signal proof of His interest in them, by a prophet's animating announcement that the Lord would that day deliver the mighty hosts of the enemy into his hand by means of a small, feeble, inadequate band. Conformably to the prophet's instructions, two hundred thirty-two young men went boldly out towards the camp of the enemy, while seven thousand more, apparently volunteers, followed at some little distance, or posted themselves at the gate, to be ready to reinforce those in front if occasion required it. Ben-hadad and his vassals and princes were already, at that early hour--scarcely midday--deep in their cups; and though informed of this advancing company, yet confiding in his numbers, or it may be, excited with wine, he ordered with indifference the proud intruders to be taken alive, whether they came with peaceful or hostile intentions. It was more easily said than done; the young men smote right and left, making terrible havoc among their intended captors; and their attack, together with the sight of the seven thousand, who soon rushed forward to mingle in the fray, created a panic in the Syrian army, who immediately took up flight. Ben-hadad himself escaped the pursuit of the victors on a fleet horse, surrounded by a squadron of horse guards. This glorious victory, won so easily, and with such a paltry force opposed to overwhelming numbers, was granted that Ahab and his people might know (Kg1 20:13) that God is the Lord. But we do not read of this acknowledgment being made, or of any sacrifices being offered in token of their national gratitude.
3 Kings (1 Kings) 20:22
kg1 20:22the prophet came to the king of Israel, and said--The same prophet who had predicted the victory shortly reappeared, admonishing the king to take every precaution against a renewal of hostilities in the following campaign.
at the return of the year--that is, in spring, when, on the cessation of the rainy season, military campaigns (Sa2 11:1), were anciently begun. It happened as the prophet had forewarned. Brooding over their late disastrous defeat, the attendants of Ben-hadad ascribed the misfortune to two causes--the one arose from the principles of heathenism which led them to consider the gods of Israel as "gods of the hills"; whereas their power to aid the Israelites would be gone if the battle was maintained on the plains. The other cause to which the Syrian courtiers traced their defeat at Samaria, was the presence of the tributary kings, who had probably been the first to take flight; and they recommended "captains to be put in their rooms." Approving of these recommendations, Ben-hadad renewed his invasion of Israel the next spring by the siege of Aphek in the valley of Jezreel (compare Sa1 29:1, with Sa1 28:4), not far from En-dor.
3 Kings (1 Kings) 20:27
kg1 20:27like two little flocks of kids--Goats are never seen in large flocks, or scattered, like sheep; and hence the two small but compact divisions of the Israelite force are compared to goats, not sheep. Humanly speaking, that little handful of men would have been overpowered by numbers. But a prophet was sent to the small Israelite army to announce the victory, in order to convince the Syrians that the God of Israel was omnipotent everywhere, in the valley as well as on the hills. And, accordingly, after the two armies had pitched opposite each other for seven days, they came to an open battle. One hundred thousand Syrians lay dead on the field, while the fugitives took refuge in Aphek, and there, crowding on the city walls, they endeavored to make a stand against their pursuers; but the old walls giving way under the incumbent weight, fell and buried twenty-seven thousand in the ruins. Ben-hadad succeeded in extricating himself, and, with his attendants, sought concealment in the city, fleeing from chamber to chamber; or, as some think it, an inner chamber, that is, a harem; but seeing no ultimate means of escape, he was advised to throw himself on the tender mercies of the Israelitish monarch.
3 Kings (1 Kings) 20:32
kg1 20:32put ropes on their heads--Captives were dragged by ropes round their necks in companies, as is depicted on the monuments of Egypt. Their voluntary attitude and language of submission flattered the pride of Ahab, who, little concerned about the dishonor done to the God of Israel by the Syrian king, and thinking of nothing but victory, paraded his clemency, called the vanquished king "his brother," invited him to sit in the royal chariot, and dismissed him with a covenant of peace.

kg1 20:34streets for thee in Damascus--implying that a quarter of that city was to be assigned to Jews, with the free exercise of their religion and laws, under a judge of their own. This misplaced kindness to a proud and impious idolater, so unbecoming a theocratic monarch, exposed Ahab to the same censure and fate as Saul (Sa1 15:9, &c.). It was in opposition to God's purpose in giving him the victory.

kg1 20:35A PROPHET REPROVES HIM. (Kg1 20:35-42)
Smite me--This prophet is supposed (Kg1 20:8) to have been Micaiah. The refusal of his neighbor to smite the prophet was manifestly wrong, as it was a withholding of necessary aid to a prophet in the discharge of a duty to which he had been called by God, and it was severely punished [Kg1 20:36], as a beacon to warn others (see on 1Ki. 13:2-24). The prophet found a willing assistant, and then, waiting for Ahab, leads the king unconsciously, in the parabolic manner of Nathan (Sa2 12:1-4), to pronounce his own doom; and this consequent punishment was forthwith announced by a prophet (see on Kg1 21:17).
