22 The prophet came near to the king of Israel, and said to him, “Go, strengthen yourself, and mark, and see what you do; for at the return of the year the king of Syria will come up against you.” 23 The servants of the king of Syria said to him, “Their god is a god of the hills; therefore they were stronger than we. But let us fight against them in the plain, and surely we shall be stronger than they. 24 Do this thing: take the kings away, every man out of his place, and put captains in their place. 25 Muster an army, like the army that you have lost, horse for horse, and chariot for chariot. We will fight against them in the plain, and surely we will be stronger than them.”
He listened to their voice, and did so. 26 It happened at the return of the year, that Ben Hadad mustered the Syrians, and went up to Aphek, to fight against Israel. 27 The children of Israel were mustered, and were provisioned, and went against them. The children of Israel encamped before them like two little flocks of young goats; but the Syrians filled the country. 28 A man of God came near and spoke to the king of Israel, and said, “Thus says Yahweh, ‘Because the Syrians have said, “Yahweh is a god of the hills, but he is not a god of the valleys;” therefore I will deliver all this great multitude into your hand, and you shall know that I am Yahweh.’” 29 They encamped one over against the other seven days. So it was, that in the seventh day the battle was joined; and the children of Israel killed one hundred thousand footmen of the Syrians in one day. 30 But the rest fled to Aphek, into the city; and the wall fell on twenty-seven thousand men who were left. Ben Hadad fled, and came into the city, into an inner chamber.
31 His servants said to him, “See now, we have heard that the kings of the house of Israel are merciful kings. Please let us put sackcloth on our bodies, and ropes on our heads, and go out to the king of Israel. Maybe he will save your life.” 32 So they put sackcloth on their bodies and ropes on their heads, and came to the king of Israel, and said, “Your servant Ben Hadad says, ‘Please let me live.’”
He said, “Is he still alive? He is my brother.” 33 Now the men observed diligently, and hurried to take this phrase; and they said, “Your brother Ben Hadad.”
Then he said, “Go, bring him.”
Then Ben Hadad came out to him; and he caused him to come up into the chariot. 34 Ben Hadad said to him, “The cities which my father took from your father I will restore. You shall make streets for yourself in Damascus, as my father made in Samaria.”
“I,” said Ahab, “will let you go with this covenant.” So he made a covenant with him, and let him go.

(Read 1 Kings 20:22-30)
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.
