311 So Moses continued to speak these words to all Israel. 2 And he said to them, "I am a hundred and twenty years old this day; I am no longer able to go out and come in. The Lord has said to me, 'You shall not go over this Jordan.' 3 The Lord your God himself will go over before you; he will destroy these nations before you, so that you shall dispossess them; and Joshua will go over at your head, as the Lord has spoken. 4 And the Lord will do to them as he did to Sihon and Og, the kings of the Amorites, and to their land, when he destroyed them. 5 And the Lord will give them over to you, and you shall do to them according to all the commandment which I have commanded you. 6 Be strong and of good courage, do not fear or be in dread of them: for it is the Lord your God who goes with you; he will not fail you or forsake you." 7 Then Moses summoned Joshua, and said to him in the sight of all Israel, "Be strong and of good courage; for you shall go with this people into the land which the Lord has sworn to their fathers to give them; and you shall put them in possession of it. 8 It is the Lord who goes before you; he will be with you, he will not fail you or forsake you; do not fear or be dismayed."

Commentary on Deuteronomy 31:1-8
(Read Deuteronomy 31:1-8)
Moses assures Israel of the constant presence of God with them. This is applied by the apostle to all God's spiritual Israel, to encourage their faith and hope; unto us is this gospel preached, as well as unto them; he will never fail thee, nor forsake thee, Hebrews 13:5. Moses 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 pleased to be admonished by Moses to be strong and of good courage. Those shall speed well, who have God with them; therefore they ought to be of good courage. Through God let us do valiantly, for through him we shall do victoriously; if we resist the devil, he will flee from us.
