John Wesley on Joshua 10:5

Of the Amorites - This name being here taken largely for any of the Canaanites, as is frequent; for, to speak strictly, the citizens of Hebron here mentioned, ver.3, were Hittites. It is reasonably supposed, that the Amorites being numerous and victorious beyond Jordan poured forth colonies into the land of Canaan, subdued divers places, and so communicated their name to all the rest.
