There is no nation ... - This is expressed in the style of Oriental hyperbole. What Obadiah means is: “there is no nation nor kingdom, of those over which he has influence, whither the king has not sent.” He could scarcely, for example, have exacted an oath from such countries as Egypt or Syria of Damascus. But Ahab may have been powerful enough to expect an oath from the neighboring Hittite, Moabite, and Edomite tribes, perhaps even from Ethbaal his father-in-law, and the kings of Hamath and Arpad.
