And when king Arad the Canaanite, which dwelt in the south, heard tell that Israel came by the way of the spies; then he fought against Israel, and took some of them prisoners. The way of the spies - אתרים atharim. Some think that this signifies the way that the spies took when they went to search the land. But this is impossible, as Dr. Kennicott justly remarks, because Israel had now marched from Meribah-Kadesh to Mount Hor, beyond Ezion-Gaber, and were turning round Edom to the south-east; and therefore the word is to be understood here as the name of a place.
