even more than the nations that Yahweh had destroyed before the people of Israel

Here "nations" refers to the people who had lived in the land of Canaan before the Israelites had arrived. Alternate translation: "even more than the people whom Yahweh had destroyed as the people of Israel advanced through the land" (See: rc://en/ta/man/jit/figs-metonymy)
