Yahweh is mocking the people and their idols. He tells the idols to save the people though he knows they cannot. (See: [[rc://en/ta/man/translate/figs-irony]])
This is saying the same thing in two ways to emphasize that idols are helpless and worthless. AT: "the wind, or even a breath, will blow them away" (See: [[rc://en/ta/man/translate/figs-parallelism]])
