Joshua 24:12

And I sent the hornet before you, in terrifying the nations of the land, Exodus 23:28; Deuteronomy 7:20, which drave them out from before you, even the two kings of the Amorites, Sihon and Og, as representatives of the entire heathen host; but not with thy sword nor with thy bow, for it was not Israel's prowess which had subdued the land.
