Elisha uses this rhetorical question to emphasize to the king that he should not kill these men. This can be written as a statement. AT: "You would not kill men that were captured as prisoners of war." or "You would not kill men taken captive in war, therefore you should not kill these men" (See: [[rc://en/ta/man/translate/figs-rquestion]])
This speaks of the king's soldiers taking men captive as if the king himself was the one who captured them. AT: "your soldiers had taken captive with their swords and bows" (See: [[rc://en/ta/man/translate/figs-metonymy]])
The king ordered his servants to prepare the food. He did not prepare the food himself. AT: "Then the king ordered his servants to prepare a lot of food for them" (See: [[rc://en/ta/man/translate/figs-metonymy]])
This means that they did not attack Israel for a long time. AT: "stopped attacking the land of Israel for a long time" (See: [[rc://en/ta/man/translate/figs-explicit]])
