29 And they encamped one over against the other seven days; and it came to pass that on the seventh day the battle was joined; and the children of Israel smote of the Syrians a hundred thousand footmen in one day. 30 And the rest fled to Aphek, into the city; and the wall fell on twenty-seven thousand men of them that were left. And Ben-Hadad fled, and came into the city, [from] chamber to chamber.
31 And his servants said to him, Behold now, we have heard that the kings of the house of Israel are merciful kings: let us, I pray thee, put sackcloth on our loins, and ropes upon our heads, and go out to the king of Israel; perhaps he will save thy life. 32 And they girded sackcloth on their loins, and ropes on their heads, and came to the king of Israel, and said, Thy servant Ben-Hadad says, I pray thee, let me live. And he said, Is he yet alive? he is my brother. 33 And the men took it as a good omen, and hastened to catch what came from him, and they said, Thy brother Ben-Hadad. ... And he said, Go, bring him. And Ben-Hadad came forth to him; and he caused him to come up into the chariot. 34 And [Ben-Hadad] said to him, The cities that my father took from thy father I will restore; and thou shalt make streets for thyself in Damascus, as my father made in Samaria. And I [said Ahab] will send thee away with this covenant. So he made a covenant with him, and sent him away.

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.
