22 Then the prophet approached the king of Israel and said to him, "Come, strengthen yourself, and consider well what you have to do; for in the spring the king of Aram will come up against you." 23 The servants of the king of Aram said to him, "Their gods are gods of the hills, and so they were stronger than we; but let us fight against them in the plain, and surely we shall be stronger than they. 24 Also do this: remove the kings, each from his post, and put commanders in place of them; 25 and muster an army like the army that you have lost, horse for horse, and chariot for chariot; then we will fight against them in the plain, and surely we shall be stronger than they." He heeded their voice, and did so. 26 In the spring Ben-hadad mustered the Arameans and went up to Aphek to fight against Israel. 27 After the Israelites had been mustered and provisioned, they went out to engage them; the people of Israel encamped opposite them like two little flocks of goats, while the Arameans filled the country. 28 A man of God approached and said to the king of Israel, "Thus says the Lord: Because the Arameans have said, "The Lord is a god of the hills but he is not a god of the valleys,' therefore I will give all this great multitude into your hand, and you shall know that I am the Lord." 29 They encamped opposite one another seven days. Then on the seventh day the battle began; the Israelites killed one hundred thousand Aramean foot soldiers in one day. 30 The rest fled into the city of Aphek; and the wall fell on twenty-seven thousand men that were left. Ben-hadad also fled, and entered the city to hide.
31 His servants said to him, "Look, we have heard that the kings of the house of Israel are merciful kings; let us put sackcloth around our waists and ropes on our heads, and go out to the king of Israel; perhaps he will spare your life." 32 So they tied sackcloth around their waists, put ropes on their heads, went to the king of Israel, and said, "Your servant Ben-hadad says, "Please let me live.' " And he said, "Is he still alive? He is my brother." 33 Now the men were watching for an omen; they quickly took it up from him and said, "Yes, Ben-hadad is your brother." Then he said, "Go and bring him." So Ben-hadad came out to him; and he had him come up into the chariot. 34 Ben-hadad said to him, "I will restore the towns that my father took from your father; and you may establish bazaars for yourself in Damascus, as my father did in Samaria." The king of Israel responded, "I will let you go on those terms." So he made a treaty 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.
