29 The two armies were poised in a standoff for seven days. On the seventh day fighting broke out. The Israelites killed 100,000 of the Aramean infantry in one day. 30 The rest of the army ran for their lives back to the city, Aphek, only to have the city wall fall on 27,000 of the survivors.
31 Then his advisors told him, "Look, we've heard that the kings of Israel play by the rules; let's dress in old gunnysacks, carry a white flag of truce, and present ourselves to the king of Israel on the chance that he'll let you live." 32 So that's what they did. They dressed in old gunnysacks and carried a white flag, and came to the king of Israel saying, "Your servant Ben-Hadad said, 'Please let me live.'" Ahab said, "You mean to tell me that he's still alive? If he's alive, he's my brother." 33 The men took this as a good sign and concluded that everything was going to be all right: "Ben-Hadad is most certainly your brother!" The king said, "Go and get him." They went and brought him back by chariot. 34 Ahab said, "I am prepared to return the cities that my father took from your father. And you can set up your headquarters in Damascus just as my father did in Samaria; I'll send you home under safe conduct." Then he made a covenant with him and sent him off.

Those about Benhadad advised him to change his ground. They take it for granted that it was not Israel, but Israel's gods, that beat them; but they speak very ignorantly of Jehovah. They supposed that Israel had many gods, to whom they ascribed limited power within a certain district; thus vain were the Gentiles in their imaginations concerning God. The greatest wisdom in worldly concerns is often united with the most contemptible folly in the things of God.
Commentary on 1 Kings 20:31-43
(Read 1 Kings 20:31-43)
This encouragement sinners have to repent and humble themselves before God; Have we not heard, that the God of Israel is a merciful God? Have we not found him so? That is gospel repentance, which flows from an apprehension of the mercy of God, in Christ; there is forgiveness with him. What a change is here! The most haughty in prosperity often are most abject in adversity; an evil spirit will thus affect a man in both these conditions. There are those on whom, like Ahab, success is ill bestowed; they know not how to serve either God or their generation, or even their own true interests with their prosperity: Let favour be showed to the wicked, yet will he not learn righteousness. The prophet designed to reprove Ahab by a parable. If a good prophet were punished for sparing his friend and God's when God said, Smite, of much sorer punishment should a wicked king be thought worthy, who spared his enemy and God's, when God said, Smite. Ahab went to his house, heavy and displeased, not truly penitent, or seeking to undo what he had done amiss; every way out of humour, notwithstanding his victory. Alas! many that hear the glad tidings of Christ, are busy and there till the day of salvation is gone.
