The speaker uses these questions to mock the king of Assyria. AT: "An ax cannot boast that it is better than the one who holds it. And a saw does not get more glory than the one who cuts with it." (See: [[rc://en/ta/man/translate/figs-rquestion]])
These phrases mean basically the same thing and are used to strengthen the meaning of the two questions before it. This can be translated as a new sentence. AT: "And neither can a rod or staff lift the person who picks it up" (See: [[rc://en/ta/man/translate/figs-parallelism]])
It is unclear whether Yahweh or Isaiah is speaking. This can be reworded so that the abstract noun "emaciation" is expressed as the verb "make weak." AT: "Therefore I, Lord Yahweh of hosts, will make the king's strongest soldiers weak" (See: [[rc://en/ta/man/translate/figs-abstractnouns]])
Yahweh compares his punishment to a fire. This emphasizes that his punishment will completely destroy all the splendor and greatness of the kingdom of Assyria. AT: "I will destroy his greatness as if I were starting a fire to burn everything he is proud of" (See: [[rc://en/ta/man/translate/figs-simile]])
