Obadiah asks this question to emphasize the danger to himself because of King Ahab's anger at Elijah. AT: "I have not wronged you ... for him to kill me." (See: [[rc://en/ta/man/translate/figs-rquestion]])
Here "no nation or kingdom" is an exaggeration that means that men have traveled very far and gone to many places to find Elijah. This can be expressed positively. AT: "my master has sent men to nations and kingdoms near and far" (See: [[rc://en/ta/man/translate/figs-hyperbole]] and [[rc://en/ta/man/translate/figs-doublenegatives]])
