6 Be strong and of good courage, do not fear nor be afraid of them; for the Lord your God, He is the One who goes with you. He will not leave you nor forsake you." 7 Then Moses called Joshua and said to him in the sight of all Israel, "Be strong and of good courage, for you must go with this people to the land which the Lord has sworn to their fathers to give them, and you shall cause them to inherit it. 8 And the Lord, He is the one who goes before you. He will be with you, He will not leave you nor forsake you; do not fear nor 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.
