Yahweh is speaking in poetry. (See: rc://en/ta/man/translate/figs-parallelism)

he has completely destroyed them, he has handed them over to the slaughter

Often prophets speak of things that will happen in the future as if they have already happened. This emphasizes the event will certainly happen. AT: "he will completely destroy them, he will give them over to the slaughter."
