Isaiah uses a question to express the difficulty of taking anything from a mighty soldier or a very strong warrior. This can be stated in active form. AT: "A person cannot take the spoils from a warrior or rescue captives from fierce soldiers." (See: [[rc://en/ta/man/translate/figs-rquestion]] and [[rc://en/ta/man/translate/figs-activepassive]])
Yahweh says that he will do what is usually impossible for people to do. This can be stated in active form. AT: "I will take the captives from the warrior, and I will rescue the spoils" (See: [[rc://en/ta/man/translate/figs-activepassive]])
