Adam Clarke on 1 Kings 20:6

Whatsoever is pleasant in thine eyes - It is not easy to discern in what this second requisition differed from the first; for surely his silver, gold, wives, and children, were among his most pleasant or desirable things. Jarchi supposes that it was the book of the law of the Lord which Ben-hadad meant, and of which he intended to deprive Israel. It is however evident that Ben-hadad meant to sack the whole city, and after having taken the royal treasures and the wives and children of the king, to deliver up the whole to be pillaged by his soldiers.
