In this verse, Ben-hadad, the king of Aram, proposes a deal to Ahab, the king of Israel. He offers to restore the cities that his father had taken from Ahab's father and allows Ahab to establish bazaars in Damascus. Ahab agrees to this proposal by saying, "I will ____ on these terms." The correct answer, "let you go," fits the context of the verse as it implies that Ahab agrees to the deal and allows Ben-hadad to leave without harm or further confrontation.
