The blessing and the curse are spoken of as if they were objects that someone will set on the mountains. Alternate translation: "some of you must stand on top of Mount Gerazim and proclaim what will cause Yahweh to bless you, and the others must stand on top of Mount Ebal and proclaim what will cause Yahweh to curse you" (See: [[rc://en/ta/man/translate/figs-metaphor]])
