29 Now the two armies kept their positions facing one another for seven days. And on the seventh day the fight was started; and the children of Israel put to the sword a hundred thousand Aramaean footmen in one day. 30 But the rest went in flight to Aphek, into the town, where a wall came down on the twenty-seven thousand who were still living. And Ben-hadad went in flight into the town, into an inner room.

31 Then his servants said to him, It is said that the kings of Israel are full of mercy: let us then put on haircloth, and cords on our heads, and go to the king of Israel; it may be that he will give you your life. 32 So they put on haircloth, and cords on their heads, and came to the king of Israel and said, Your servant Ben-hadad says, Let me now keep my life. And he said, Is he still living? he is my brother. 33 Now the men took it as a sign, and quickly took up his words; and they said, Ben-hadad is your brother. Then he said, Go and get him. So Ben-hadad came out to him and he made him get up into his carriage. 34 And Ben-hadad said to him, The towns my father took from your father I will give back; and you may make streets for yourself in Damascus as my father did in Samaria. And as for me, at the price of this agreement you will let me go. So he made an agreement 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.
