And the Lord, he it is that doth go before thee,.... The Word of the Lord, his Shechinah, according to the above Targum, and so in the next clause; the same that brought Israel out of Egypt, had gone before them in the wilderness, and now would go before Joshua and them into the land of Canaan: he will be with thee; to guide and direct, to assist and strengthen, to protect and defend, to give success to his arms, and victory over his enemies: he will not fail thee, neither forsake thee; not fail to give him counsel and direction, to afford him strength, and to fill him with courage, and to deliver his enemies into his hands; nor forsake him till he had finished the work he was to do, had made a complete conquest of the Canaanites, and settled the people of Israel in their land: fear not, neither be dismayed; at the number and strength of the enemy, nor at any difficulties that might lie in the way of finishing so great an undertaking, since the Lord would be with him; see Rom 8:31.
