1 Kings 20:2

It may be supposed that a considerable time had passed in the siege, that the city had been reduced to an extremity, and that ambassadors had been sent by Ahab to ask terms of peace short of absolute surrender, before Ben-hadad would make such a demand. He would expect and intend his demand to be rejected, and this would have left him free to plunder the town, which was evidently what he desired and purposed.
