Ben-hadad said to him, “I will restore the cities my father took from your father; you may set up your own marketplaces in Damascus, as my father did in Samaria.” “By this treaty I release you,” Ahab replied. So he made a treaty with him and sent him away.

Even in his inner chamber he feared, and would, if he could, flee further, though none pursued. His servants, seeing him and themselves reduced to the last extremity, advised that they should surrender at discretion, and make themselves prisoners and petitioners to Ahab for their lives, Kg1 20:31.
Commenting on 1 Kings 20:31-43
And Benhadad said unto him,.... The word Benhadad is not in the original text, and some, as Osiander and others, have thought they are the words of Ahab last spoken of; which seems most likely, who not only took Benhadad into his chariot, but in his great and superabundant kindness, though the conqueror, said to him what follows: the cities which my father took from...
streets for thee in Damascus--implying that a quarter of that city was to be assigned to Jews, with the free exercise of their religion and laws, under a judge of their own. This misplaced kindness to a proud and impious idolater, so unbecoming a theocratic monarch, exposed Ahab to the same censure and fate as Saul (Sa1 15:9, &c.).
