Jeremiah uses these questions to show his distress about seeing the battle flag and hearing the sound of the horn for such a long time. He wishes that the battle would end soon. It can be stated as an exclamation. AT: "Oh, how I wish that the battle would end, and the flag would be lowered, and the sound of the army's horn would stop" (See: [[rc://en/ta/man/translate/figs-rquestion]])
It can be stated clearly that Yahweh says this. This is probably his reply to Jeremiah, telling why the battle is still happening. AT: "Yahweh replied, 'It is because of the foolishness of my people ... do not know to do good.'" (See: [[rc://en/ta/man/translate/figs-explicit]])
