The living God - Compare the marginal reference. The gods of the pagan are "dead idols." On the names of the seven nations, see Genesis 10:16, etc., note.

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.

And Joshua said,.... To the people as follows:

hereby ye shall know that the living God is among you; who has life in and of himself, and is the author of life to all his creatures; and is so called in opposition to the lifeless idols of the Gentiles: and it may be, as Abarbinel observes, to suggest to them, that though Moses was dead, the Lord lived, and lives for evermore; and by the following miracle of dividing the waters of Jordan, it would be a plain case that the Lord was yet among them, to protect and defend them, deliver and save them:

and that he will without fail drive out from before you the Canaanites, and the Hittites, and the Hivites, and the Perizzites, and the Girgashites, and the Amorites, and the Jebusites; all the seven nations are mentioned, even the Girgashites, who are sometimes omitted, to assure them of the expulsion of them all, to make way for their entire possession of the land of Canaan, as had been promised them.

And Joshua said, {d} Hereby ye shall know that the living God is among you, and that he will without fail drive out from before you the Canaanites, and the Hittites, and the Hivites, and the Perizzites, and the Girgashites, and the Amorites, and the Jebusites.

(d) By this miracle in dividing the water.

3:10 Ye shall know - By experience and sensible evidence. The living God - Not a dull, dead, senseless God, such as the gods of the nations are; but a God of life, and power, and activity to watch over you, and work for you. Among you - Is present with you to strengthen and help you.

3:7-13 The waters of Jordan shall be cut off. This must be done in such a way as never was done, but in the dividing of the Red sea. That miracle is here repeated; God has the same power to finish the salvation of his people, as to begin it; the WORD of the Lord was as truly with Joshua as with Moses. God's appearances for his people ought to encourage faith and hope. God's work is perfect, he will keep his people. Jordan's flood cannot keep out Israel, Canaan's force cannot turn them out again.
