So Joshua struck all the land, the hill country, the Negev (South country) and the lowland and the slopes [that descend to the Dead Sea] and all their kings. He left no survivor, but he utterly destroyed all who breathed, just as the Lord, the God of Israel, had commanded.

and to the kings who were in the north, in the hill country, and in the Arabah [the plain] south of Chinnereth (the Sea of Galilee) and in the lowland and on the hills of Dor on the west;

in the hill country, in the lowland (foothills), in the Arabah [plain], on the slopes [descending to the Dead Sea], and in the wilderness, and in the Negev (South country)—the [lands of the] Hittite, the Amorite and the Canaanite, the Perizzite, the Hivite and the Jebusite:
