Adam Clarke Bible Commentary

Hereby ye shall know that the living God is among you - The Israelites were apt to be discouraged, and to faint at even the appearance of danger; it was necessary, therefore, that they should have the fullest assurance of the presence and assistance of God in the important enterprise on which they were now entering. They are to combat idolaters, who have nothing to trust in and help them but gods of wood, stone, and metal: whereas they are to have the living God in the midst of them - He who is the author of life and of being - who can give, or take it away, at his pleasure; and who by this miracle proved that he had undertaken to guide and defend them: and Joshua makes this manifestation of God the proof that he will drive out the Hittites, Hivites, etc, before them. With regard to the situation of each of these nations in the land of Canaan, Calmet remarks, that those called Canaanites chiefly inhabited what is called Phoenicia, the environs of Tyre and Sidon: the Hittites occupied the mountains, southward of the promised land: the Hivites dwelt by Ebal and Gerizim, Sichem and Gibeon, towards the mountains of Hermon: the Perizzites were probably not a distinct nation or tribe, but rather villagers, scattered through the country in general: the Girgashites possessed the country beyond the Jordan, towards the lake of Gennesareth: the Jebusites possessed Jerusalem: and the Amorites occupied the mountainous country in the vicinity of the western part of the Dead Sea, and also that part of the land of Moab which the Israelites conquered from Sihon and Og.
