John Gill's Bible Commentary Ver. 3. The Lord thy God, he will go over before thee , etc.] This he said to encourage the people of Israel; that though he should die, and not go over with them, their ever living and true God, the great Jehovah, the Lord of hosts, he would go before them, and fight their battles for them; so that they had nothing to fear from their enemies: [and] he will destroy those nations from before thee ; the seven nations which then inhabited the land: and thou shalt possess them ; their countries, cities, and houses, fields, and vineyards: [and] Joshua, he shall go over before thee ; as their general to fight for them, subdue their enemies, and put them into the possession of the land, and divide it to them: as the Lord hath said ; ( Deuteronomy 3:28).
Matthew Henry Commentary
Verses 1-8 - Moses assures Israel of the constant presence of God with them. This i applied by the apostle to all God's spiritual Israel, to encourag their faith and hope; unto us is this gospel preached, as well as unt them; he will never fail thee, nor forsake thee, Heb 13:5. Mose commends Joshua to them for a leader; one whose wisdom, and courage and affection they had long known; one whom God had appointed to be their leader; and therefore would own and bless. Joshua is well please to be admonished by Moses to be strong and of good courage. Those shal speed well, who have God with them; therefore they ought to be of goo courage. Through God let us do valiantly, for through him we shall d victoriously; if we resist the devil, he will flee from us.
